The effects of radon, if found in food or drinking water, are unknown. Following ingestion of radon dissolved in water, the biological half-life for removal of radon from the body ranges from 30 to 70 minutes.
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Radon concentration varies greatly with season and atmospheric conditions. For instance, it has been shown to accumulate in the air if there is a meteorological inversion and little wind. [81] High concentrations of radon can be found in some spring waters and hot springs. [82]
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 hazardous elements found in NORM are radium 226, 228 and radon 222 and also daughter products from these radionuclides. The elements are referred to as "bone seekers" which when inside the body migrate to the bone tissue and concentrate. This exposure can cause bone cancers and other bone abnormalities.
Alternatively, radon may enter the body through contaminated drinking water or through the decay of ingested radium [3] – making radon diffusion one of the greatest dangers of radium. [10] Thus, 222 Rn is a carcinogen ; in fact, it is the second leading cause of lung cancer in the United States after cigarette smoking , [ 3 ] with over 20,000 ...
A particular problem is encountered with naturally generated radon gas which can affect instruments that are set to detect contamination close to normal background levels and can cause false alarms. Because of this skill is required by the operator of radiological survey equipment to differentiate between background radiation and the radiation ...
The thyroid is found in the neck, and is responsible for producing hormones that in turn play a role in metabolism, growth and development in children, temperature regulation and in the ...
