If you lived within 50 miles of a nuclear power plant, you would receive an average radiation dose of approximately 0.01 millirem per year. To put this into perspective, the average person in the United States receives an exposure of 300 millirem per year from natural sources of background radiation. What are the health risks of exposure to ionizing radiation? Modern nuclear reactors are well designed to prevent radiation leakage and alarm systems are designed to signal each time a leak occurs. As an additional safety measure, all workers will wear dosimeters to monitor their individual exposure levels.
Researchers reported that the analysis of the remaining Canadian nuclear workers (93.2 percent) provided no evidence of increased risk, and the risk estimate was consistent with the estimates that form the basis of radiation protection standards. While these studies have been conducted in the context of nuclear energy workers, the results apply to professionals in related fields, such as medicine and science, who may also be exposed to low doses of radiation in the course of their employment. In addition, researchers claim that in this study, less than 5% of workers in the nuclear industry received the maximum cumulative radiation dose of 100 millisieverts throughout their careers, and most of those doses were received in the early days of the nuclear industry, when radiation protection standards were minors. rigorous.
Although the recent explosion at the Fukushima power plant in Japan has not yet shown any acute effect on those most exposed to radiation, the incident itself created negative attitudes towards nuclear power and the nuclear power plant. In fact, many nuclear power plant workers are more concerned with issues such as fires, explosions and radiation leaks, rather than being naturally exposed to radiation during routine work. Extensive epidemiological studies of nuclear power plant workers have shown that working in a nuclear power plant is not a risky occupation. Human exposure to I-131 released by accidents at nuclear power plants stems mainly from the consumption of contaminated water, milk, or food.
Based on those estimates, researchers say that about 1 to 2% of all deaths among workers in the nuclear industry can be attributed to radiation exposure. The individual dosimeters of nuclear power plant workers since the 1940s have been maintained and available for analysis to correlate them with the long-term health of workers. However, researchers say that many of the more than 400,000 nuclear workers who participated in the study worked in the early days of the nuclear industry and were exposed to much higher radiation doses than current standards.

Radioactive isotopes released in nuclear power plant accidents include iodine-131 (I-13), cesium-134 (Cs-13) and Cs-137.
