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 radon could be coming in from one of any of the tunnels that lead into the building, Goelzhauser said. "It's a little early right now to know exactly what we need to do to fix the problem," he ...
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L. At the same time it is also recommends that people think about fixing their homes for radon levels between 2 pCi/L and 4 pCi/L. [ 98 ] In the United Kingdom the ...
