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.
Radon mixed with hydrogen entered the evacuated system through siphon A; mercury is shown in black. Radon was discovered in 1899 by Ernest Rutherford and Robert B. Owens at McGill University in Montreal. [48] It was the fifth radioactive element to be discovered, after uranium, thorium, radium, and polonium.
January is National Radon Action Month, raising awareness on the colorless, odorless gas that is the second leading cause of lung cancer in the U.S. Radon testing still extremely important in ...
Radium and radon are important contributors to environmental radioactivity. Radon occurs naturally as a result of decay of radioactive elements in soil and it can accumulate in houses built on areas where such decay occurs. Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe. [1]
There are different levels of home inspection services, and you can upgrade your inspection to include specialties, such as testing for radon or searching for mold. Naturally, these extra services ...
But skipping this important step is not recommended. Inspections provide you with an unbiased expert assessment of the property and help you make an informed decision on the purchase.
To achieve these aims, WHO has formed a network of key partner agencies from some 40 Member States. This network is the basis for the WHO International Radon Project which was launched in 2005. Working groups will collect and analyse information on radon risk, radon policies, radon mitigation and prevention as well as risk communication.
EPA recommends that all homes should be monitored for radon. If testing shows levels less than 4 picocuries radon per liter of air (160 Bq/m 3), then no action is necessary. For levels of 20 picocuries radon per liter of air (800 Bq/m 3) or higher, the home owner should consider some type of procedure to decrease indoor radon levels. [1]
