Some air pollutants are transported far beyond their points of release. For example, otherwise pristine areas have received acid precipitation originating from industrial smokestack emissions hundreds of miles away. Dust from the Sahara Desert in Africa has been detected in South America, and radioactive debris from the Chernobyl nuclear reactor meltdown has been deposited in countries throughout Europe. 

Cancer Risks The increased risk of thyroid cancer after thyroid irradiation in childhood has been recognized for nearly 50 years (Dolphin, 1968). Thus, a major concern of therapy relates to the risk of thyroid cancer. Detractors of therapy point to the increased rates of thyroid cancer and thyroid nodules observed in young children exposed to radiation from nuclear fallout at Hiroshima or after the Chernobyl nuclear reactor explosion. 

Nuclear weapons production and testing facilities (Hanford, WA, Savannah River, GA, Rocky Flats, CO, and The Nevada Test Site, in the United States, and Mayak in the former Soviet Union), also released small amounts. The releases occurred in accidents with nuclear weapons, the reentry of satellites that used Pu-238, and by the Chernobyl nuclear reactor accident. 

Cs is produced by reprocessing of nuclear fuel. Cs is generally present in the atmosphere as a result of nuclear weapons testing, though undoubtedly the Chernobyl nuclear reactor explosion has made a major contribution to environmental levels of Cs [5]. 

The Chernobyl nuclear reactor accident caused several reviews to be made of the DOE weapons nuclear facilities by the National Research Coimcil. While no imminent safety hazards were identified, a number of suggestions were made to improve nuclear safety.
