The few accidents have been spectacular and newsworthy, but of little consequence in terms of human fatalities.The novelty value and hence newsworthiness of nuclear power accidents remains high in contrast with other industrial accidents, which receive comparatively little news coverage.
Apart from Chernobyl, no nuclear workers or members of the public have ever died as a result of exposure to radiation due to a commercial nuclear reactor incident.Most of the serious radiological injuries and deaths that occur each year (2-4 deaths and many more exposures above regulatory limits) are the result of large uncontrolled radiation sources, such as abandoned medical or industrial equipment.(There have also been a number of accidents in experimental reactors and in one military plutonium-producing pile – at Windscale, UK, in 1957, but none of these resulted in loss of life outside the actual plant, or long-term environmental contamination.) See also Table 2 in Appendix.The use of nuclear energy for electricity generation can be considered extremely safe.Every year several thousand people die in coal mines to provide this widely used fuel for electricity.Other controls include physical shielding and limiting the time workers spend in areas with significant radiation levels.
These are supported by continuous monitoring of individual doses and of the work environment to ensure very low radiation exposure compared with other industries.The lessons from nearly one hundred years’ experience mean that reputable airlines are extremely safe.In the chemical industry and oil-gas industry, major accidents also lead to improved safety.There is wide public acceptance that the risks associated with these industries are an acceptable trade-off for our dependence on their products and services.With nuclear power, the high energy density makes the potential hazard obvious, and this has always been factored into the design of nuclear power plants.Those improvements are both in new designs, and in upgrading of existing plants.
