Radioactive pollution can come from natural sources like cosmic rays and radioactive elements in the Earth's crust, or from human sources such as nuclear weapons testing, nuclear power plants, medical use of radioisotopes, and improper disposal of radioactive waste. Exposure to radiation can cause both immediate effects like hair loss and long term effects like cancer. All living things are vulnerable but some organisms preferentially accumulate specific radioactive materials. Control of radioactive pollution requires safe containment and storage of wastes, along with preventative measures to limit radiation exposure.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

How to Build a Module in Odoo 17 Using the Scaffold MethodCeline George
Odoo provides an option for creating a module by using a single line command. By using this command the user can make a whole structure of a module. It is very easy for a beginner to make a module. There is no need to make each file manually. This slide will show how to create a module using the scaffold method.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Radioactive pollution
1.
2. Definition of Radio Active Pollution
• Radioactive pollution, also called radiological
contamination, is the deposition of, or
presence of radioactive substances on
surfaces or within solids, liquids or gases
(including the human body), where their
presence is unintended or undesirable.
3. Sources of Environmental Radiation
• Natural (Background) Radiation:
• This includes cosmic rays that reach the
surface of the earth from space and terrestrial
radiations from radioactive elements present
in the earth’s crust.
• Many radioactive elements such as radium
224, uranium 235, uranium 238, thorium 232,
radon 222, potassium 40 and carbon 14 occur
in rocks, soil and water.
4. Man-made Radiation
• This includes mining and refining of plutonium
and thorium production and explosion of nuclear
weapons, nuclear power plants, nuclear fuels and
preparation of radioactive isotopes.
• Production of nuclear weapons involves the tests
of nuclear arms. These tests produce large
amount of radioactive elements into the
environment and make other materials also
radioactive. They include strontium 90, cesium
137, iodine 131 and some others.
5. Atomic Reactors and Nuclear Fuels
• Wastes from atomic reactors also contain
radioactive materials. The biggest problem is
the disposal of these radioactive wastes. If
these wastes are not properly disposed off,
can harm the living organisms wherever they
may be dumped. Inert gases and halogens
escape as vapours and cause pollution as they
settle on land or reach surface waters with
rain.
6.
7. Radioisotopes
• Many radioactive isotopes such as 14C. 125I, 32P
and their compounds are used in scientific
research. Waste waters containing these
radioactive materials reach water sources like
rivers through the sewers. From water they
enter human body through food chains.
8. X-rays and Radiation Therapy
• Human beings also voluntarily receive
radiation from diagnostic X-rays and radiation
therapy for cancer.
• People working in power plants, nuclear
reactors, fuel processors or living nearby are
vulnerable to radiation exposure.
9. Effects of Radioactive Pollution
• Radiations have both immediate or short-
range and delayed or long-ranged effects.
10. (i) Short Range (Immediate) Effects
• They appear within days or a few weeks after
exposure. The effects included loss of hair,
nails, subcutaneous bleeding, change in
number and proportion of blood cells,
changed metabolism, and proportion of blood
cells, etc.
11. (ii) Long Range (Delayed) Effects
• They appear several
months or even years
after the exposure. The
effects are caused by
development of genetic
changes, mutations,
shortening of life span,
formation of tumour,
cancers, etc. The effect
of mutations can persist
in the human race.
12. Cont…
• All organisms are affected by radiation
pollution. Some organisms preferentially
accumulate specific radioactive materials. For
example, oysters accumulate 65Zn, fish
accumulate 55Fe, marine animals
accumulate 90Sr.
13. Control of Radioactive Pollution
The following preventive measures should be
followed to control radioactive pollution.
• Leakage of radioactive materials from nuclear
reactors, industries and laboratories using them
should be totally stopped.
• Radioactive wastes disposal must be safe. They
should be changed into harmless form or stored
in safe places so that they can decay in a
harmless manner. Radioactive wastes only with
very low radiation should be discharged into
sewerage.
14. Cont…
• Preventive measures
should be taken so that
natural radiation level
does not rise above the
permissible limits.
• Safety measures should
be taken against accidents
in nuclear power plants.
15. Cont….
• There is no full proof method of disposal of
radioactive wastes.
• In many cases radioactive wastes are sealed in
steel drums and sunk into sea for their natural
decay.
16. Cont….
• But it poses serious problems as radioactive
isotopes can produce not only immediate
effects on living organisms but also produce
mutations in genetic material which could
have serious problems for later generations.
• Malformation of body organs at birth,
abnormality in organ development are some
of the effects observed in lab animals.
