This document discusses the effects of radiation exposure from nuclear plants. It explains that ionizing radiation can break chemical bonds and cause cancer, while exposure leads to symptoms like nausea, fatigue, hair loss, and organ damage. Two particularly dangerous radioactive materials released are cesium-137 and iodine-131. Cesium-137 accumulates in the environment, while iodine-131 is absorbed by the thyroid and can cause tumors, especially in children. The conclusion is that radiation from nuclear events is very dangerous and it is important to limit exposure time outside.
Possible health effects of nuclear crisis
Ionizing radiation can break chemical bonds and cause health effects like nausea, fatigue, vomiting, hair loss and diarrhea. Exposure to 500,000 microsieverts can cause nausea and fatigue within hours, while 750,000 microsieverts leads to hair loss within a few weeks. A million microsieverts can cause hemorrhaging and 4 million microsieverts usually leads to death. The Chernobyl disaster directly caused 50 deaths within months and is estimated to eventually cause 4000 radiation-related deaths.
Indian ocean tsunami
A tsunami is a series of waves caused by the displacement of water, usually in an ocean. Tsunamis are most often caused by earthquakes, volcanic eruptions, underwater explosions, and meteorite impacts. The effects of tsunamis are devastating and include widespread destruction and damage, death, injury, and financial losses measured in millions of dollars. Communities are also affected by long-lasting psychological trauma for survivors. Tsunamis in Banda Aceh, Indonesia in 2004 caused massive destruction and loss of life when powerful waves hit without warning.
Report2
This document discusses the effects of radiation exposure on the human body. It provides information on different radiation measurement units and outlines health effects that occur at various radiation dosage levels, such as above 100 rems causing nausea and vomiting. It also discusses historical radiation incidents like Hiroshima, Nagasaki, Three Mile Island, and Chernobyl, noting many initial deaths were due to radiation exposure and survivors often later developed cancers. The document stresses radiation effects may occur decades later and treatment options are limited for high dosage exposures.
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.
Effect of radiation
The document discusses the effects of radiation exposure on people. It provides examples of major radiation exposures from nuclear incidents in Hiroshima and Nagasaki, Three Mile Island, and Chernobyl. These incidents caused many deaths from both the initial blasts and subsequent radiation exposure. The document emphasizes that while nuclear energy can be dangerous if not properly handled or regulated, lessons can be learned from past accidents to improve safety.
Tropicalcyclones
Cyclones are violent storms characterized by rotating winds around a low-pressure center. They form when warm, high-pressure air rises and cooler, low-pressure air moves in, causing the air to rotate into a funnel. Countries most affected by cyclones include Bangladesh, India, Thailand, and countries near the Indian Ocean. Cyclones can bring heavy winds over 150 kph, torrential rain, storm surges over 12 meters high that flood coastal areas. Hurricanes are a specific type of cyclone that occurs in the Atlantic Ocean and have wind speeds over 74 mph. They can cause widespread damage through high winds, heavy rainfall, and storm surges.
Cyclones!!!!
Cyclones are violent tropical storms that form over tropical waters and involve the circulation of warm and cool air masses. They can cause heavy rain, flooding, and strong winds that damage homes and infrastructure. Countries most affected by cyclones include Bangladesh, India, Thailand, Malaysia, Indonesia, and Sri Lanka due to their locations near the Indian Ocean. Pakistan has experienced two major cyclones, the first in 1948 that killed over 1,000 people and the second in 1999 that caused damage but no deaths in Karachi.

This is a powerpoint presentation report about Floods and Tsunami. I'm gonna share this ppt that I created to help some students out there. Enjoy :)
Lightning
Lightning is caused by hot air rising and cold air rushing in to fill the space, bumping ice crystals in clouds and creating an electrical charge. It is dangerous to be outside or near metal during a lightning storm, as lightning can strike trees, fences, pipes, and more. Some key safety tips are to get indoors if you hear thunder, avoid swimming or being near bodies of water, and don't touch metal or use wired phones if a storm is occurring.
Disaster management
Group 1 contains the names and roll numbers of 9 students.
The document introduces different types of disasters, including natural disasters like earthquakes, tsunamis, and man-made disasters such as nuclear leaks, terrorism.
Effective disaster management is needed because disasters can cause loss of life, property damage, and long-term environmental and health impacts. Authorities provide guidelines to stay safe during disasters and prevent further damage.
ramana tornado
Tornadoes are localized, violently destructive windstorms characterized by a funnel-shaped cloud extending to the ground. They most commonly occur in the central United States, forming from thunderstorms when hot and cold air mix. Tornadoes can be classified as either water-supported or land-supported, with land-supported tornadoes causing more damage upon contact with the ground. Tornadoes pose serious risks, as they are capable of causing significant property damage, injuries, and loss of human life.
Science prjt 3
Tsunamis are large waves generated by earthquakes or other disturbances that displace large volumes of water. They can reach beaches in minutes and cause extensive damage. A major 2004 tsunami in Sri Lanka killed over 40,000 people after an earthquake in the Indian Ocean. Hurricanes are violent tropical storms with winds over 74 mph that form over warm ocean waters and move westward. They can only dissipate over land or cooler waters. Floods occur when water overflows river banks or other areas, sometimes within hours but sometimes over days, causing billions in annual damage in the US. Drought is a period of unusually dry weather lacking precipitation that can last years and seriously damage crops and water supplies. Tornadoes form from thunder

Lecture cyclone 1
Bangladesh is prone to cyclones due to its geographic location in the Bay of Bengal. Cyclones develop over the warm waters of the Bay, gaining energy, before tracking westward towards Bangladesh. The country's low-lying delta lands provide no protection from high winds and storm surges. Some of the deadliest cyclones in history have impacted Bangladesh, such as the devastating 1970 Bhola cyclone that killed 300,000 people. Common impacts of major cyclones include heavy rainfall, flooding, and high winds that can lead to widespread damage. Climate change is also expected to increase the risks from cyclones and sea level rise in Bangladesh in the future.
Tsunami Rk
Tsunamis are large sea waves caused by underwater earthquakes or volcanic eruptions. They mostly occur in the Pacific Ocean and can be dangerous in shallow waters. The shoreline may retreat before the first wave hits, and while the initial wave may not be the largest, tsunamis consist of a series of waves. Famous tsunamis destroyed parts of Sri Lanka, Phuket, and Okushiri Island in Japan.
Japan earthquake 2011
1) On March 11, 2011, a magnitude 9.0 earthquake struck the Tohoku region of Japan, generating a powerful tsunami that caused widespread damage.
2) Over 18,000 people were killed or missing as a result of the earthquake and tsunami. The Fukushima Daiichi nuclear power plant was damaged, displacing over 350,000 evacuees.
3) While the situation at Fukushima was dangerous, it was brought under control and radiation levels, though concerning, did not reach Chernobyl-level meltdown. Financial support, donations, and messages of care and encouragement can help with recovery efforts.
Tsunami Rk
Tsunamis are large sea waves caused by underwater earthquakes or volcanic eruptions. They mostly occur in the Pacific Ocean and can consist of a series of waves where the first wave is not necessarily the largest. When a tsunami is approaching, the shoreline will briefly retreat from the beach rather than approaching.

Emergency Management Data
This document analyzes data from a survey of 119 emergency management professionals in Ontario municipalities. It finds that:
- 52% of primary CEMCs are fire chiefs, while 40% have other primary roles and 8% have emergency management as their only role.
- 80% of all CEMCs (primary and alternate) have primary roles other than emergency management, meaning they have "double hats".
- Only 20% of CEMCs have emergency management as their sole daily responsibility.
The document examines charts breaking down these roles and responsibilities in more detail and concludes there may be conflicts between primary positions and emergency management duties for many CEMCs.
Emergency management ontario and the provincial nuclear
The document discusses Emergency Management Ontario (EMO) and Ontario's Provincial Nuclear Emergency Response Plan (PNERP). EMO is responsible for emergency management in Ontario and maintains the PNERP, which includes plans for responding to nuclear emergencies at facilities and during transportation.

Possible health effect_of_radiation
This document discusses the different types of radiation and their health effects. It outlines ionizing radiation, which can break down body structures and cause nausea, fatigue, hair loss, and death at high levels. Two types of radiation from Fukushima are cesium-137, which can cause sarcoma and contaminate foods/water, and iodine-131, which can cause thyroid tumors but can be prevented with iodine tablets. The document concludes by noting the need to monitor radiation levels until Fukushima is stopped and consider new energy resources to replace nuclear power.
Possible health effects_of_nuclear_crisis_1
The document discusses the potential health effects of radiation exposure from the Fukushima nuclear crisis. It explains that there are two types of radiation: non-ionizing and ionizing. Ionizing radiation, which includes gamma rays and X-rays, can cause cancer if a person is exposed in large enough doses. Symptoms of radiation exposure include nausea, fatigue, vomiting, hair loss and diarrhea. The document also notes that radioactive iodine and cesium emitted from the Fukushima plant can be absorbed by the body and pose health risks, particularly to children, if exposure levels are high enough. It concludes that while not all radiation is dangerous, increased exposure could raise cancer risks.
Nuclear radiation effects
The document discusses the effects of radiation on health from the Fukushima Daiichi nuclear disaster. It explains that there are two types of radiation: non-ionizing and ionizing. Ionizing radiation is more dangerous and can cause cancer. Exposure to radiation can initially cause nausea, fatigue and vomiting, and higher exposures may lead to hair loss, diarrhea, destruction of the intestinal lining, and eventually death. Cesium-137 and iodine-131 are particularly dangerous isotopes released during nuclear accidents. The document concludes by noting the sievert measurement of radiation dose and the types of sickness that different doses can cause.
Nuclear radiation health_effects
1) Authorities sheltered over 170,000 people within 12 miles of the nuclear plant and distributed iodine tablets to those within 20 miles. At least 200 people were exposed to radiation.
2) Radiation is categorized as ionizing or non-ionizing. Ionizing radiation like x-rays and gamma rays is more dangerous as it can destroy chemical bonds and cause cancer.
3) Effects of radiation exposure depend on duration but initially include nausea, tiredness, vomiting, and later hair loss, diarrhea, and potentially organ damage and death at higher exposures.
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.

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.
1kome
Ionizing radiation can cause health effects depending on the duration of exposure. Cesium-137 and iodine-131 are especially dangerous because iodine-131 is absorbed by the thyroid gland where it can cause tumors, and it has a short half-life of 8 days, posing risks especially to children. Small doses of radiation over a lifetime that total 10,000 microsieverts may result in 5-6 additional cancer deaths per 10,000 people exposed compared to those not exposed.
assignment2
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.
S1180190 1
This document discusses different types of radiation and their effects. It compares ionizing radiation, which can break chemical bonds and cause cancer, to non-ionizing radiation, which does not break bonds and is generally not harmful. It describes the symptoms a person exposed to ionizing radiation may experience, from initial nausea and fatigue to organ damage and death depending on exposure level. It also distinguishes radiation effects from a nuclear explosion, which produces lethal gamma rays and long-lived radioactive fallout, from a nuclear plant accident like Fukushima, which emits radioactive cesium and iodine. Cesium-137 and Iodine-131 are highlighted as particularly dangerous due to their ability to contaminate food and water supplies.
Health effect of nuclear crisis
Ionizing radiation can be harmful by breaking molecules like DNA and causing cancer. The effects of radiation exposure include initial nausea and fatigue, then potential hair loss, diarrhea, organ damage, and eventually death at high levels. While nuclear power plants operate at lower uranium concentrations than nuclear bombs, radiation from the Fukushima crisis included dangerous iodine-131 and cesium-137 isotopes. Exposure levels over 500,000 microsieverts can cause short-term sickness, and doses over 1 million microsieverts lead to further health issues.
Article1
There are two types of radiation: non-ionizing radiation like infrared, radio waves, and cell phone radiation that we are exposed to in daily life which does not destroy chemical bonds or cause cancer. Ionizing radiation like X-rays and gamma rays is much more dangerous and can be emitted during nuclear power plant accidents, spreading radioactive materials like radioactive iodine and cesium with half-lives of up to 30 years that can contaminate crops.

Radiation
This document discusses different types of radiation and their effects. It describes:
1) Radiation is the transfer of energy through space or matter. It includes electromagnetic radiation like radio waves and x-rays.
2) Humans and organisms are exposed to both ionizing radiation, which can damage cells, and non-ionizing radiation like infrared light, which has weaker thermal effects.
3) Ionizing radiation comes from natural sources like cosmic rays and radioactive elements in the ground, as well as man-made sources like nuclear weapons, power plants, medical imaging, and nuclear accidents.
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.

Possible health effects_of_nuclear_crisis
The document discusses the possible health effects of nuclear crises and radioactivity. It describes accidents at Fukushima and Hiroshima/Nagasaki that exposed many people to radiation. Radioactivity can cause nausea, dizziness, hair loss, leukemia, various cancers, and other sicknesses by exposing people to poisonous radioactive substances like uranium, potassium, and iodine. The conclusion is that radioactivity has extensive negative impacts on human health.
Nuclear pollution
Nuclear pollution occurs when radioactive substances or radiation contaminate the environment. Major sources include nuclear power plants and nuclear weapons testing. Nuclear pollution can affect all life forms and potentially cause mutations, cancer, and death depending on radiation exposure levels. While nuclear power has benefits, it also produces hazardous nuclear waste and accidents can release radiation. Proper handling, storage, and containment of radioactive materials and waste is needed to control nuclear pollution and its severe health impacts.
Speaking&writing3 slide1
The document discusses the dangers of radiation from nuclear power plants and nuclear bombs. It notes that radiation within 20 miles of a power plant can be dangerous, and that people within 12 miles of the Fukushima plant were able to take shelter. It also explains that there are two types of radiation: ionizing radiation, which can cause cancer, and nonionizing radiation, which is safer and used in devices like microwaves and cell phones. Exposure to high levels of ionizing radiation from a nuclear bomb or accident can cause nausea, tiredness, vomiting, hair loss, diarrhea, and increased risk of death.
The radiation effects to health
This document discusses the different types of radiation and their effects on human health. There are two main types - ionizing radiation, which can break chemical bonds and cause cancer, and non-ionizing radiation, which is not believed to cause cancer. Ionizing radiation includes X-rays and gamma rays and can cause nausea, fatigue, vomiting, hair loss, diarrhea, dehydration, and death depending on the exposure level and length of time exposed. Nuclear bombs produce dangerous ionizing radiation in the form of X-rays and gamma rays that can accumulate in food and lead to cancer, as was tragically demonstrated by the atomic bombings of Hiroshima and Nagasaki which killed over 166,000 people initially and

The document discusses the establishment of a tsunami warning system in the Indian Ocean following the devastating 2004 Indian Ocean earthquake and tsunami. Key points include:
1) Several countries installed pressure gauges in the ocean to directly detect tsunami wave movement and share data with meteorological agencies.
2) Scientists study past earthquakes and tsunamis to simulate scenarios and choose the most appropriate forecast when a tsunami occurs.
3) The Japan Meteorological Agency initially provided tsunami forecasts for countries around the Indian Ocean, but responsibility has transitioned to Regional Tsunami Watch Providers consisting of local countries.
4) Challenges remain in fully informing all people of warnings and establishing comprehensive evacuation plans
Report
The 2004 Indian Ocean earthquake and tsunami killed over 230,000 people due to the lack of an early warning system. In response, countries around the Indian Ocean established a Regional Tsunami Watch Providers system to detect tsunamis and quickly notify member countries within 10 minutes. However, challenges remain in fully informing all at-risk populations and strengthening cooperation between countries. Effective tsunami warning systems require sustained funding, public education, and regional coordination.

- 1. Does Nuclear Cricis effects health? S1180194 Masato Harada
- 2. Fukushima I nuclear accidents Fukushima I nuclear accidents is severe nuclear accide nt. Large radionuclide was released. As a result, 170,000 people within 12 miles of the plant have to escape place of refuge. And, at least 200 people hav e been exposed to radiation. Are they all right? How Does Nuclear Cricis effects health?
- 3. Nocuous of radiation ・ There are two types of radiation(non-ionizing and ionizing) ・ Non-ionizing is safe. For example, infrared radiation, radio wave, cellphone radiation and microwave are Non-ionizing. ・ Ionizing is harmful. It breaks chemical bonds and causes cancer.For example, X-rays, gamma rays and alpha or beta rays are Ionizing. Generally speaking ,it means radiation.
- 4. Influence of Radiation ・ Influence of person caused by radioation depends on how long you are exposed. ・ The initial symptoms are same as adverse by radiation tratment. For example, vomiting, diarrhea and hair loss deserve it. ・ Severe symptoms are destruction of the intestinal lining and worse diarrhea and dehydration, then central nervous system damage. In the worst case, it causes death.
- 5. Comparison between the accident and nuclear bomb ・ The accident is different from explosion of nuclear bomb. ・ Explosion of nuclear bomb produce X-rays and gamma rays They make mushroom cloud which includes cesium-137, iodine-131, radioactive strontium and a host of other long-lived byproducts of the explosion and sheds radioactive subatance kill many people. ・ Fukushima does not release X-rays and gamma rays. Most of radioactive subatance which is radiocesium and radioiodine, which is generated in a process of atomic power generation. Of course, they are harmful to human being, too.
- 6. Iodine-131 and Cesium-137 ・ Iodine-131 and Cesium-137 are released by nuclear accident. ・ If people absorb Iodine-131 , the possibility that people might contract cancer of the thyroid will rise. I In fact, many people contractd it and die in Chernobyl. It is confirmed that it is released in Fukushima.But, Iodine tablet can restrain the symptom. ・ Cesium-137 is danger like Iodine-131. It has a half-life of 30 years. So,Chernobyl became land which is not suitable for living. It is also confirmed that it is released in Fukushima.
- 7. Damage by radiation ・ The biological risk of exposure to radiation is measured in sieverts. ・ Dose limit of ordinary person is 1 millisieverts a year and one of radiation worker is 50 millisieverts a year. ・ A dose of 2000 millisieverts causes hair loss and bleeding and kills 5 percent people. One from 3000 to 5000 millisieverts kill 50 percent people and cause cataract and erythema. One of 7000 or more kill 99 percent people.
- 8. Matters to be attended to Fukushima I nuclear accidents is the worst nuclear accident. A lot of people are very concerned about safty of nuclear power plant and groundless rumors are abroad. I think that people should take care of following heads. ・ Take care of rumors. ・ Don`t do overreaction. ・ Get right knowledge about radioactivity. ・ Understand that different experts may have different opinions about damage by radioactivity. ➲
