The document discusses the effects of radiation exposure on humans and some historical radiation accidents. It begins by defining the unit of measurement for radiation dosage as the rem. Exposure between 25-100 rems can cause detectable changes in blood but usually no immediate harm, while over 100 rems risks radiation sickness. Doses over 300 rems cause hair loss and internal harm, and over 800 rems is always fatal. It then summarizes the radiation effects of the Hiroshima and Nagasaki bombings, the Chernobyl accident, and the Three Mile Island incident. The document concludes that current medical treatment is ineffective against potentially fatal radiation doses, so prevention of radiation accidents is important.

The rem is the unit used to measure radiation dosage, with higher doses causing more harm to living tissue. Doses of 25-100 rems can cause detectable changes but no immediate harm, while doses over 100 rems cause radiation sickness symptoms like nausea and vomiting. Doses over 450 rems result in death for half of those exposed, and doses over 800 rems are always fatal. Survivors of radiation exposure also face increased long-term cancer risks. Both the atomic bombings of Hiroshima and Nagasaki and the Chernobyl disaster released radiation that caused many deaths from initial exposure and later illnesses. While there are no effective treatments for high radiation doses, treatments for lower doses include blood transfusions and
Electrocution
Electrocution, or death caused by electric shock, occurs when electric current passes through the body. The type and severity of injury depends on factors like voltage, current, duration of contact, and path of current. Death is usually due to cardiac fibrillation or respiratory paralysis. Burns may be present at entry and exit points. A forensic examination looks for these burns, as well as other injuries like fractures caused by muscle contractions. Tissue damage ranges from mild burns to charring, and internal injuries can include heart lesions or cerebral edema.

High voltage electrical injuries commonly cause cardiac arrhythmias or respiratory arrest due to muscle paralysis. Management involves treating the direct tissue damage and secondary organ failures. Prevention through safety measures is important to reduce electrical injuries.
Therapuetic dc
1) Direct current refers to a continuous flow of electricity in one direction. Therapeutic direct current is applied for over 1 second and can cause sensory stimulation, hyperemia, and electrotonus in tissues.
2) Direct current is transmitted through wet pads or sponges in contact with the skin. Over time, chemical changes and electrolysis may occur near the electrodes.
3) Direct current can be used to accelerate wound healing, reduce pain through sensory stimulation, and destroy unwanted tissues at high densities through coagulation and liquefaction near the electrodes. Precautions must be taken with neoplastic or infected tissues.
Ele safty
Electrical safety is the top priority area for industries as electrical accidents can cause fatalities. Some key risks include electric shock, electrical burns, and fires. The risk of electric shock depends on voltage, current, resistance of the body, and other factors. Industries must implement proactive safety management programs that focus on controlling equipment and material performance, as well as human performance through proper training and use of personal protective equipment. Reactive approaches like emergency plans and first aid treatment are also important.
Comparison: Lightning Injury, Electrical Injury
This document discusses nursing management for patients who have experienced lightning or electrical injuries. It provides background information on lightning and electrical injuries, including common myths. It then discusses the purpose of a student research project which explored the most effective nursing interventions to manage long-term neurological and psychiatric sequelae in adults following such injuries. The methods, results, limitations and implications for nursing management are summarized.
Nuclear pollution
Radioactive substances are present naturally and undergo decay, emitting particles and radiation until becoming stable. There are two sources of radioactivity: natural sources like cosmic rays, radon and materials in the soil, air and water. Anthropogenic or man-made sources are nuclear power plants, medical uses of radiation, and other applications using radioactive materials. Radiation can damage living things by causing genetic mutations that affect future generations or somatic effects like cancer and other illnesses. Careful siting of nuclear plants and proper disposal of radioactive waste can help control nuclear pollution.
Electricity and Electrical Injuries
Electricity can cause significant harm if it passes through the human body. The amount of damage depends on several factors, particularly the voltage and current magnitude, and the path the electricity takes through tissues. While low-voltage shocks may cause little issue, high voltages over 1,000V can lead to extensive tissue destruction along the current path. Alternating currents are generally more dangerous than direct currents due to muscle tetany and inability to release contact. Treatment requires assessing for burns, trauma, and medical complications along with monitoring for delayed effects on the brain, nerves and heart. Installing residual current detectors in homes can help prevent many electric injuries.
Electrical Injuries
1) Electrical injuries can range from mild tingling to fatal depending on the current, its path through the body, and duration of exposure. Household currents are typically 110-220V and 1mA-300mA while industrial settings have 120-460V or higher and currents up to 6A.
2) When responding to an electrocution, the top priority is to ensure the power source is disconnected before touching the victim. Additional hazards in industrial settings include higher voltages that can cause extensive tissue damage.
3) For high voltage electrocutions over 1000V, the current will take the shortest path to ground, potentially causing entrance and exit wounds with internal tissue damage. Specialized response is required and power
Shock
Shock is a physiological state characterized by a significant systemic reduction in perfusion resulting in decreased tissue oxygen delivery. The causes of shock include hypovolumic, cardiogenic, neurogenic, anaphylactic, septic, and obstructive shock. The management of shock involves initial assessment of vital signs, resuscitation focusing on airway, breathing, and circulation, urgent investigation to identify the underlying cause, and appropriate treatment of the cause such as fluids for hypovolumic shock, inotropes for septic shock, and adrenaline with antihistamines for anaphylactic shock. The mortality from septic and cardiogenic shock remains high.
Electrical injuries Dr Ashutosh
This document discusses various types of electrical injuries including:
1. Joule burns, flash or spark burns, and crocodile flash burns caused by electricity passing through skin.
2. Judicial electrocution which uses alternating current of 1700-1800V for 60 seconds to cause third degree burns and brain temperatures of 600C.
3. Lightning injuries can cause superficial, irregular burn markings called filigree or arborescent burns, as well as fusion of metal objects.
Nuclear hazards
The document discusses nuclear hazards and radiation. It defines nuclear reactions like fusion and fission, and notes they can release energy. The main sources of nuclear radiation are natural sources like radon, and anthropogenic sources like nuclear power plants and accidents. Exposure to radiation above certain levels can cause health effects ranging from mild sickness to death. The Chernobyl disaster of 1986 in Ukraine resulted from a power surge and explosions, releasing radiation over Europe. It required large evacuations and has been linked to increased cancer rates. Shielding, distance and limiting exposure time can help control radioactive pollution risks.
Electrical Safety, Humidity And Scavenging
This document discusses electrical safety, humidity, and scavenging in anesthesia. It covers topics such as Ohm's law, direct and alternating current, electrical shock hazards, methods of measuring humidity, importance of humidification and hazards of over-humidification, sources of waste anesthetic gases, components of operating room ventilation systems, and components of passive and active scavenging systems.
Radioactive pollution
Radioactive pollution is defined as the emission of radioactive substances into the environment from human activities like nuclear processes, weapons production, mining, and medical and power generation waste. Sources include natural cosmic and terrestrial radiation as well as man-made activities. Exposure to radiation can damage DNA and lead to health issues like cancer depending on the duration and level of exposure. Preventive measures include limiting nuclear tests and waste, careful disposal, and treatment methods to reduce radioactivity in the environment.
Electrical safety in biophysical measurements
This document discusses various methods for protecting patients, visitors, and staff from electrical hazards in healthcare facilities, including macro-shocks and micro-shocks. It outlines the importance of grounding systems, isolation transformers, ground fault circuit interrupters (GFCIs), leakage current reduction, insulation standards for medical equipment classes, isolation amplifiers, and periodic safety testing using electrical safety analyzers. The overall goal is to eliminate electric connections to the heart and minimize hazards through grounding, insulation, and monitoring of leakage currents and voltages.
Electrical safety precautions and Electric shocks
The document provides safety tips for working with electricity. It advises turning off the power source before attempting to fix electrical issues. Proper grounding is important to prevent electric shock, such as using three-prong plugs and ground fault circuit interrupters. Never assume the power is off and always check yourself. In emergencies of electric shock, call emergency services rather than treating the victim yourself.
Medical Electrical Safety
This document provides an overview of electrical safety testing for medical equipment. It discusses the various classes and types of medical equipment and the electrical safety tests that should be performed on each.

Radiation effect on_humans
Exposure to radiation can cause various health effects depending on the dosage. A dose of 25 rems may cause detectable changes in blood work, while doses over 100 rems risk radiation sickness with symptoms like nausea and vomiting. Exposure over 300 rems can cause temporary hair loss but more internal harm, and doses over 800 rems are always fatal. The atomic bombings of Hiroshima and Nagasaki killed many from radiation exposure rather than the explosions directly. Major nuclear accidents like Chernobyl and Three Mile Island exposed workers and communities to radiation due to cooling system failures and reactor explosions, demonstrating radiation's health risks. Currently there is no effective medical treatment for high radiation doses.

Radiations can affect human health and cause symptoms like nausea, vomiting, and hair loss. Exposure to radiation decreases white blood cells and can lead to cancers like leukemia and lung cancer. The atomic bombs dropped on Hiroshima and Nagasaki in 1945 exposed many people to high levels of radiation and caused much suffering. Nuclear power plant accidents like at Three Mile Island have also led to radiation exposure incidents. While radiation has medical uses like cancer treatment, excessive exposure can have negative health effects.
Impact of radiation pollution on human health siri
This document provides an overview of radiation pollution and its impact on human health. It discusses various sources of radiation pollution including nuclear explosions, weapons production, mining, power plants and medical procedures. Three types of radiation pollution are described: continuous, occasional, and accidental. The effects of radiation pollution on human health can be instantaneous, delayed, or prolonged. Factors like radiation dose, duration of exposure, and individual sensitivity influence its impact. Radiation can damage human cells and lead to conditions like cancer, mental retardation, and hereditary effects. The Chernobyl accident is presented as a case study.

The document discusses the effects of radiation exposure on humans, including units of measurement for radiation dosage, symptoms of radiation sickness from doses over 100 rems, and real-life high radiation exposure events like Hiroshima, Nagasaki, Three Mile Island, and Chernobyl. There is currently no effective medical treatment for potentially fatal radiation doses.
Radiation effects
The document discusses units of measurement for radiation and fallout, effects of radiation exposure on human health, and major radiation accidents. The REM is used to measure radiation exposure levels, with 25 REMs potentially causing blood changes, 100 REMs being generally harmless, and over 450 REMs resulting in death for half of those exposed. Radiation can cause nausea, vomiting, hair loss, and damage cells over time. Major accidents releasing radiation included the bombings of Hiroshima and Nagasaki and the Chernobyl nuclear plant disaster.
A Rational Environmentalist’s Guide to Nuclear Power
Nuclear fission is the most dangerous form of large-scale electric power generation, except all those other forms that have been tried.
Environmental Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed 9 million people in the world.
Major forms of pollution include Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution.
An environmental hazard is a substance, a state, or an event that has the potential to threaten the surrounding natural environment / or adversely affect people's health, including n]] and natural disasters such as storms and earthquakes.
Any single or combination of toxic chemical, biological, or physical agents in the environment, resulting from human activities or natural processes, that may impact the health of exposed subjects, including pollutants such as heavy metals, pesticides, biological contaminants, toxic waste, industrial and home chemicals.
Human-made hazards while not immediately health-threatening may turn out detrimental to man's well-being eventually, because deterioration in the environment can produce secondary, unwanted negative effects on the human ecosphere. The effects of water pollution may not be immediately visible because of a sewage system that helps drain off toxic substances. If those substances turn out to be persistent (e.g. persistent organic pollutants), however, they will literally be fed back to their producers via the food chain: plankton -> edible fish -> humans. In that respect, a considerable number of environmental hazards listed below are man-made (anthropogenic) hazards.
Hazards can be categorized in four types:
1. Chemical
2. Physical (mechanical, etc.)
3. Biological
4. Psychosocial Hazards

Radiation protection
A former Russian spy named Litvinenko died of radiation poisoning in the UK. Tests found high levels of polonium-210, a radioactive substance, in his urine. Experts said polonium-210 is dangerous if ingested or inhaled and can spread throughout the body and damage major organs. Litvinenko's death was described as unprecedented in the UK and he was apparently poisoned by radiation.
Ionising radiation and living things
Radiation can kill or change living cells. The biological effects of radiation depend on the type of radiation, the absorbing tissue, and the total absorbed energy. Different types of radiation have different effects on cells due to their varying abilities to ionize atoms. While natural background radiation exposes people to around 2 millisieverts per year, high doses from events like nuclear accidents or weapons can cause immediate illness and death due to damage to skin, blood, and other tissues. Long-term effects include increased cancer risk believed to be caused by radiation damaging DNA and altering cell reproduction.

RADIOACTIVE POLLUTION
INTRODUTION
Radiation And Radioactivity:
The application of radioactive elements in nuclear weapons, X-rays, MRI and other medical equipment causes their exposure to human beings.
The deposition of these radioactive gases in water bodies also cause radioactive contamination.
Radiation is the transport of energy through space.
Two types of radiation. - Ionizing radiation
- Non ionizing radiation
Sources of radioactive pollution
Natural sources of radiation: Natural sources of radiation are mentioned below:
In natural sources of radioactive pollution, atomic radioactive minerals are one among them.
Cosmic rays possess high energy ionizing electromagnetic radiation.
Another source of radioactive radiation is naturally occurring radioisotopes. Radioisotopes are found in soil in small quantity.
Radioactive elements like radium, thorium, uranium, isotopes of potassium and carbon occur in lithosphere
Anthropogenic sources of radiation
Human activities mentioned below include in sources of radioactive pollution:
Nuclear tests
Nuclear reactors
Diagnostic medical applications
Nuclear Wastes
Nuclear explosions
Nuclear metal processing
Nuclear Reactor Accidents
Almost 99 such nuclear accidents have been occur through out worldwide. 56 of 99,have been occurred only in USA.
Kyshtym, Russia (former Soviet Union) – 29,september,1957 (INES Level 6)
200 people died on direct radiation and almost 8000 people died in 32 years of this nuclear accidents
Major nuclear accidents
Three Mile Island, United States – 28 March, 1979 (INES Level 5)
one of the elements of the power plant’s system malfunctioned
Chernobyl, Ukraine (former Soviet Union) – 26,april,1986 (INES Level 7)
A series of events led to the explosion of the reactor number four at the Chernobyl Nuclear Power Plant
Fukushima, Japan –11,march 2011 (INES Level 7)
9.0 magnitude earthquake struck off the coast of Japan. The resulting tsunami (49 feet tall) hit the Fukushima I Nuclear Power Plant 51 and experienced meltdown
NUCLEAR BOMBS
August 6, 1945, Hiroshima
directly killing an estimated 80,000 people. By the end of the year, injury and radiation brought total casualties to 90,000–140,000
On August 9, 1945, Nagasaki
Almost 75,000 people died and more affected by radiation.
Radiation Health Effects
Radionuclides are carcinogens and at high doses can also cause rapid sickness and death.
The health effects of exposure to radiation depend on many factors.
the amount of energy it deliver
the length of exposure time
the organs and tissues exposed
characteristics of the exposed person
How does radiation injure people?
High energy radiation breaks chemical bonds.
This creates free radicals, like those produced by other insults as well as by normal cellular processes in the body.
The free radicals can change chemicals in the body.
These changes can disrupt cell function and may kill cells.
Nuclear Energy
It opens up to innovate the grey areas of nuclear energy or alternate forms of energy to generate electricity
Possible health effects
Ionizing radiation from the Fukushima nuclear accident poses health risks. Exposure to high levels of radiation can cause nausea, hair loss, hemorrhaging and death. While radiation levels near Fukushima are elevated, levels in Tokyo are only 10 times higher than normal which is still considered very low and unlikely to cause immediate health effects. However, Japan will need to monitor long term health consequences from the accident.
Nuclear hazard
Radioactive pollution poses risks to human health and the environment. Sources of radiation include natural sources like cosmic rays and radioactive materials in the Earth's crust, as well as man-made sources from nuclear power generation, medical technology, mining, and nuclear weapons testing and fallout. Exposure to radiation can cause both acute and long-term health effects depending on dose, radiation type, and exposure duration, ranging from radiation sickness to cancer and genetic mutations. Proper disposal and containment of nuclear waste, along with safety regulations and monitoring, are needed to reduce risks from radioactive pollution.
Nuclear plant radiation 2
The document discusses the health effects of radiation exposure from nuclear incidents. It provides examples of exposure levels and their effects on human health, including nearly 100rem causing nausea and vomiting, and over 300rem potentially causing organ damage and death. It summarizes radiation incidents at Three Mile Island and Chernobyl, where Chernobyl is classified at the highest level on the International Nuclear Event Scale. The conclusion emphasizes the importance of radiation prevention and careful exposure given the potential lethal effects from over 300rem of exposure.
Radioactive wastes
This document discusses radioactive wastes and their health and environmental effects. It defines key terms like radiation, ionizing radiation, and radionuclides. It describes different sources of radiation exposure including natural sources like radon and human-made sources like medical devices. It outlines the different types of radiation such as alpha particles, beta particles, and gamma rays. It also discusses the health effects of radiation exposure such as acute radiation syndrome from high doses and increased cancer risk from low doses.
NUCLEAR HAZARDS
This document presents information on nuclear hazards from a group presentation. It discusses radioactive pollution and its sources from natural occurrences like cosmic rays and radioactive materials in the earth's crust, as well as man-made sources such as nuclear power plants, nuclear weapons, and mining. Nuclear accidents can cause meltdowns when temperatures rise too high in nuclear reactors. The effects of nuclear hazards include cancer, reduced lifespan, and genetic mutations in organisms and future generations. Examples of major nuclear accidents provided are at Three Mile Island, Goiania, Chernobyl, and Fukushima. Preventing nuclear hazards involves containment, isolation of wastes, and dilution of wastes.
Biological effects of radiations
Ionizing radiation can damage biological molecules like DNA by breaking bonds or removing electrons. This damage can lead to cell malfunctions and potentially cancer if the DNA is not repaired properly. The main types of ionizing radiation that can cause this damage are alpha particles, beta particles, gamma rays, X-rays, and UV radiation. Nonionizing radiation like light and microwaves only heat samples but large amounts are needed to cause harm, while ionizing radiation can cause damage even at low doses. Radiation exposure comes from natural sources like radon gas, as well as medical procedures and other human activities.
Radioactive+thermal pollution
Radioactive pollution occurs when radioactive material is released into the environment, usually as a byproduct of nuclear power generation or other applications of nuclear technology. The main types of radioactive waste are low-level waste, intermediate-level waste, and high-level waste. Exposure to radiation can damage DNA and lead to health issues like cancer or death, with effects varying based on the level and duration of exposure. Thermal pollution is another type of pollution caused by the release of heated water, often from power plants and industrial facilities, which can raise water temperatures and lower oxygen levels, harming local wildlife. Strict safety measures and monitoring are needed to prevent radioactive and thermal pollution.

It notes that Japanese culture can be described based on five values: collectivism, uncertainty avoidance, power distance, masculinity, and high-low context. For each of these values, the document provides an example of how a website could be customized to reflect that cultural aspect, such as displaying a CEO's message to reflect power distance or using specific colors that carry meaning in Japan to reflect high-low context.
Massive_earthquake_strikes_Chile
A massive 8.8 magnitude earthquake struck central Chile, killing at least 214 people and causing widespread damage. Buildings and roads were destroyed, and electricity, water, and phone lines were cut off in many areas. Tsunamis generated by the earthquake swept ashore in other countries in the Pacific, but caused little damage. The earthquake was the largest to hit Chile in 50 years. Rescue efforts were hampered by collapsed bridges and structures. Aftershocks continued to cause damage, including collapsed buildings in Santiago. Many residents were left homeless after the disaster. Chile is vulnerable to large earthquakes due to its location along the Pacific Ring of Fire.
July 18 july_24_possible_health_effects_of_nu
The document discusses the potential health effects of radiation exposure from the Fukushima Daiichi nuclear power plant crisis. It explains that ionizing radiation can break chemical bonds and cause cancer if exposure levels are high enough. Initial symptoms of radiation sickness include nausea, fatigue and vomiting, while very high exposure leads to organ damage, loss of consciousness and death. Certain radioactive isotopes like Cesium-137 and Iodine-131 are especially dangerous if ingested due to accumulation in soft tissues and the thyroid gland. The document provides exposure levels in microsieverts that correspond to different health effects ranging from mild sickness to death.
Article 3
The Indian Ocean Tsunami warning system detects potential tsunamis through a network of seismographic and ocean monitoring stations across the Indian Ocean. When an earthquake occurs, data is transmitted to warning centers in Hawaii and Japan to analyze and issue watches or warnings. National warning agencies are meant to communicate these to other countries, though coordination could be improved. At the local level, organizations work to educate communities on tsunami safety and how to respond to warnings.
July 18 july_24_possible_health_effects_of_nu
Ionizing radiation from nuclear plants and explosions can damage human health by breaking chemical bonds and causing cancer. The effects depend on exposure time, with initial symptoms being nausea and fatigue and higher exposures potentially causing organ damage, loss of consciousness, and death. Two types of radiation produced by nuclear reactions - cesium-137 and iodine-131 - are especially dangerous as they can accumulate in food and water and irradiate the body from inside over long periods of time due to their long half-lives. Exposure levels over 500,000 microsieverts can make people sick within hours or weeks depending on dose.
How the indian_cean_tsunami
The document summarizes how the Indian Ocean tsunami warning system works. Following the devastating 2004 tsunami, an early warning system was created by the Intergovernmental Oceanographic Commission. A network of seismographic and ocean monitoring stations was established across the Indian Ocean to detect potential tsunamis. Data is transmitted to warning centers in Hawaii and Japan who analyze it to determine the size of earthquakes and issue watch alerts. While technology has improved monitoring, warnings do not always reach all affected areas due to issues with infrastructure, language barriers or technology limitations.

This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.
From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Radiation effect on_humans
- 1. Article #2 Radiation Effects on Humans
- 2. Units of Measurement The unit used to measure radiation dosage is the rem. which stand for roentgen equivalent man. It represents the amount of radiation needed to produce a particular amount of damage to living tissue.
- 3. Effects of Radiation Exposure on Human Health Exposure of Just 25 rems causes some detectable changes in blood, doses to near 100 rem usually have no immediate harmful effects. Doses above 100 rems cause the first signs of radiation sickness including. 1 nausea 2vomiying 3headache 4some loss of white blood cell Doses of 300 rems or more cause temporary hair loss, but more significant internal harm. dose of 800 rems or more are always fatal.
- 4. Hiroshima and Nagasaki Many people at Hiroshima and Nagasaki died not directly from the actual explosion,but from the radiation released as a result of the explosion. the doctors who is in Hiroshima and Nagasaki Didn't know the causes and how to cure radioactive patient .
- 5. Chernobyl the Chernobyl nuclear accident is summarized as a mismanaged electrical engineering experiment which resulted in the reactor exploding. the explosion was chemical, driven by gases and steam generated by the core runaway,not by nuclear reactions.
- 6. The Mile Island nuclear worker head big noises coming from nuclear plants. some 220 gallons of water per minute began flowing out of the reactor vessel . Within five minutes after the main feed water system failed,the rector, deprived of all normal and emergency sources of cooling water, and no longer able to use its enormous energy to generate electricity. the loss of coolant at the reactor continued for some 16 hours. Abort a third of the core melted down.
- 7. Medical Treatment there is currently no effective medical treatment available for potentially fatal radiation doses.Medical science has no way of telling the difference between people who have received fatal doses and will die despite all effects and can be saved includes blood transfusion and bone marrow transplants.
- 8. Summary Radiation effects on humans of great account. And the medical curing don't find. so we should prevent radiation accidents.
