(39,166 posts)"The accident at the Chernobyl nuclear power plant in 1986 was a tragic event for its victims, and those most affected suffered major hardship. Some of the people who dealt with the emergency lost their lives. Although those exposed as children and the emergency and recovery workers are at increased risk of radiation-induced effects, the vast majority of the population need not live in fear of serious health consequences due to the radiation from the Chernobyl accident. For the most part, they were exposed to radiation levels comparable to or a few times higher than annual levels of natural background, and future exposures continue to slowly diminish as the radionuclides decay. Lives have been seriously disrupted by the Chernobyl accident, but from the radiological point of view, generally positive prospects for the future health of most individuals should prevail."

"People who were evacuated in 1986, received an average, whole-body radiation dose of 20 mSv, and a dose to the thyroid (from iodine-131) of 470 mSv. Inhabitants of the most highly contaminated parts of Belarus, Russia, and Ukraine, where deposition of cesium-137 was higher than 555 kBq per m2, received the whole body doses of 47 mSv, 36 mSv, and 83 mSv, respectively. The average doses to the thyroid in the most contaminated regions were 177 mGy in the Gomel district (Belarus), 37 mGy in the Bryansk district (Russia), and 380 mGy in the 8 most contaminated districts of Ukraine."

"In Colorado, for example, natural radiation exposure can be 1000 mrem per year due to higher altitude." Chernobyl evacuees received, on average, the same whole-body radiation dose as someone living in Colorado for two years. In 2013 average levels in Chernobyl are .417 mSv/hr, or 3.7x as high as naturally-occurring radiation in Colorado.
