Radon-222 decay products have been classified by the International Agency for Research on Cancer as being carcinogenic to humans, and as a gas that can be inhaled, lung cancer is a particular concern for people exposed to elevated levels of radon for sustained periods. During the 1940s and 1950s, when safety standards requiring expensive ventilation in mines were not widely implemente… WebbRadon is a gas formed by the breakdown of uranium, a natural radioactive material found in all soil and rock. Long-term exposure to radon is the 2nd leading cause of lung cancer after smoking and the leading cause of lung cancer for people who have never smoked.

WebbEfforts to establish either absolute or relative risk factors for radon daughter exposures have been hampered by a number of confounding influences, including other constituents of mine atmospheres (e.g., heavy metals, diesel fumes), the smoking history of the miners, and in many instances, inadequate documentation of work histories and causes of death. http://www.icrpaedia.org/index.php/Calculating_Radon_Doses flame alchemy
