Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
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 ...
Pb as observed in Japan as a function of time, due to variations in radon concentration. [4] Radon concentration in the atmosphere is usually measured in becquerels per cubic meter (Bq/m 3), which is an SI derived unit. As a frame of reference, typical domestic exposures are about 100 Bq/m 3 indoors and 10–20 Bq/m 3 outdoors.
Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe. [1] Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2]
The contamination resulted in a $333 million settlement in 1996. The clean-up process is ongoing as of 2022, with monthly monitoring reports submitted by PG&E. [69] This case has led to California being the only state in the US to adopt an MCL of 10 ppb specifically for hexavalent chromium instead of relying on an overall total chromium count. [70]
This month, the EPA wants you to think about the air you breathe and take action against a health threat you probably didn't know existed: Radon gas. Along with the many useful and sometimes ...
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 good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
