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.
After 11 half-lives (42 days), radon radioactivity is at 1/2 000 of its original level. At this stage, the predominant residual activity is due to the radon decay product 210 Pb, whose half-life (22.3 years) is 2 000 times that of radon, and its descendants 210 Bi and 210 Po, totalling 0.03% of the initial seed activity.

Short-term radon test devices used for initial screening purposes are inexpensive, in some cases free. There are important protocols for taking short-term radon tests and it is imperative that they be strictly followed. The kit includes a collector that the user hangs in the lowest habitable floor of the house for two to seven days.
In fact, radon is the second leading cause of lung cancer in Idaho, according to the health department. About two of every five homes in the state that have been tested for radon have levels above ...
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]
Working in a kibbutz that was ravaged by Hamas’ Oct. 7 attack, Otmazgin — a volunteer commander with ZAKA, an Israeli search and rescue organization — saw the body of a teenager, shot dead ...
The other debunked account originated from Otmazgin's colleague, Yossi Landau, also a longtime volunteer working in Be’eri. In the days and weeks that followed the attack, Landau told global media what he thought he saw: a pregnant woman lying on the floor, her fetus still attached to the umbilical cord wrenched from her body.
Footage showed New Orleans crowds enjoying New Year's Eve celebrations before an attack that left at least 14 people dead and dozens injured. A truck ploughed into a crowd of revellers on Bourbon ...
