A number of spas that treat visitors with naturally infused radon water from the local hills were founded in 1906 and onwards in Jáchymov, Czech Republic, and still exist today. [6] These spas were world-renowned, as evidenced by an article in the New Zealand Thames Star Supplement from 1912 (the article uses the Austrian name of the town ...
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.

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.
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 ...
Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
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.
She was taking college courses at the time of the attacks and had never traveled to the U.S. until 2003 when she made a trip to New York with her mother. Head has remained out of the public eye ...
