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] For instance, as radon has a half-life of four days, opening the windows once a day can cut the mean radon concentration to one fourth of its level.
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Jan. 18—ATHENS — January is National Radon Action month, and each year University of Georgia Cooperative Extension sponsors a poster contest for students across the state to help bring ...
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.
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]
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 ...
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 ...
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. Allowable concentrations in uranium mines are approximately 1,220 Bq/m 3 (33 pCi/L) [ 103 ]
