More than 26% of Erie County homes tested for radon between 2010 and 2020 have detected levels that equal or exceed the Environmental Protection Agency's "action level" of 4 picoCuries per liter ...
Under this modeling, the best policy is obviously to reduce the radon levels of all homes where the radon level is above average, because this leads to a significant decrease of radon exposure on a significant fraction of the population; but this effect is predicted in the 0–200 Bq/m 3 range, where the linear model has its maximum uncertainty ...
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
The radon levels in some of the mines can reach 400 to 700 kBq m −3. [ 17 ] A common unit of exposure of lung tissue to alpha emitters is the working level month ( WLM ), this is where the human lungs have been exposed for 170 hours (a typical month worth of work for a miner) to air which has 3.7 kBq of 222 Rn (in equilibrium with its decay ...
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 ...

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.
Four (4.0) picocuries per liter is the "action level" above which remedial action should be taken, said Ryan Goelzhauser, a certified radon mitigation specialist with Popham Construction.
