The Institute of Environmental Management and Assessment (IEMA) is the largest professional body for environmental practitioners in the United Kingdom and worldwide, with nearly 20,000 members. [ 1 ] Members receive updates on current environmental law and legislation, and the group organises over 100 regional events on environmental topics to ...
Illinois Emergency Management Agency-Office of Homeland Security (IEMA-OHS) is an agency of the state of Illinois responsible for preparing for and coordinating responses to emergencies. It replaced the Illinois Civil Defense Agency in 1975 under House Bill 1109.
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
The public needs to be aware of radon risks and the means to reduce and prevent these." [2] In 1996 [citation needed], WHO published a report containing several conclusions and recommendations covering the scientific understanding of radon risk and the need for countries to take action in the areas of risk management and risk communication.
Radium and radon are in the environment because they are decay products of uranium and thorium. The radon (222 Rn) released into the air decays to 210 Pb and other radioisotopes, and the levels of 210 Pb can be measured. The rate of deposition of this radioisotope is dependent on the weather.
Radon concentrations can vary daily, and accurate radon exposure estimates require long-term average radon measurements in the spaces where an individual spends a significant amount of time. [ 172 ] Radon levels fluctuate naturally, due to factors like transient weather conditions, so an initial test might not be an accurate assessment of a ...
