The School Health Policies and Practices Study (SHPPS), conducted by the CDC in 2012, found that of schools located in counties with high predicted indoor radon levels, only 42.4% had radon testing policies, and a mere 37.5% had policy for radon-resistant new construction practices. [59]
Radon test kits can be purchased by calling the Illinois Radon Hotline at 800-325-1245 or at most hardware and department stores. It is recommended to conduct one short-term test and one long-term ...
In a working mine, the radon level can be controlled by ventilation, sealing off old workings and controlling the water in the mine. The level in a mine can go up when a mine is abandoned; it can reach a level which can cause the skin to become red (a mild radiation burn). The radon levels in some of the mines can reach 400 to 700 kBq m −3. [17]
Very high radon concentrations (>1000 Bq/m 3) have been found in houses built on soils with a high uranium content and/or high permeability of the ground. If levels are 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.
Radon and its isotopes, parent radionuclides, and decay products all contribute to an average inhaled dose of 1.26 mSv/a (millisievert per year). Radon is unevenly distributed and varies with weather, such that much higher doses apply to many areas of the world, where it represents a significant health hazard.
In fact, indoor air can hold levels of certain pollutants that are up to five times higher than found outdoors. Air purifiers can indeed neutralize some of the risks posed by indoor air pollution ...

Developing evidence-based public health guidance for Member States to formulate policy and advocacy strategy including the establishment of radon action levels; Development of approaches for radon risk communication. To achieve these aims, WHO has formed a network of key partner agencies from some 40 Member States. This network is the basis for ...
