Sources Of Radioactive Emissions

One of the common sources of radioactive emissions is the emission of radiation from nuclear power plants. Nuclear power plants generate heat and electricity by splitting atoms through a process known as nuclear fission. As a result, they release radiation in the form of gamma rays and other particles which can be registered as radiation. Although the radiation released from nuclear power plants is very low and cannot be felt, it is still possible to detect the radiation and it can cause health risks if exposed. Other sources of radioactive emissions include uranium mining, nuclear weapons, and the burning of fossil fuels. Uranium is a radioactive material essential for nuclear energy production and nuclear weapons. The emission of radiation from these activities is due to the natural decay of the uranium. As well, when fossil fuels such as coal, natural gas, and petroleum are burned, radiation is released due to the burning of uranium and other radioactive materials contained within them. Nuclear accidents also produce radiation in the form of gamma rays and other particles. The most recent nuclear accident was the Fukushima Daiichi disaster in Japan in 2011, which released large amounts of radiation into the atmosphere. Finally, humans are also exposed to very low levels of naturally occurring radiation. Natural radioactivity occurs in rocks, soil, air, water, and even in our bodies due to the radioactive decay of elements such as potassium-40 and uranium-238. However, due to extremely low levels of radiation emitted, the contribution of naturally occurring radiation to human exposure is generally minimal.
