The efﬂorescence environmental effects ensuing from the use of fossil fuels are the discharge, during the burning action, of contents like brown ash, CO2, all oxides of nitrogen , SO2 and traces of heavy materials. Carbon dioxide (CO2), methane (CH4), nitrogen oxide (NO2) and two chloroﬂuorocarbon (CFCl3 and CF2Cl2) make the ambiance hold heat and thus lead to greenhouse warming. Contamination from fossil fuels is darned for 24,000 early deaths each year in the U.S. alone. However, as with all energy sources, there is some deﬁlement related with defend actions such as manufacturing and expatriation. The National Council on Radiation Protection and Measurements (NCRP) reckoned the average out radioactivity per short ton of coal is 17,100 millicuries/4,000,000 tons in terms of net radioactive discharge . With 154 coal plants in the U.S.A, this quantities to expelling of 0.6319 TBq per year for a scoop plant, which still does not straightaway equate to the ﬁxes on nuclear plants , as coal emissions hold long lived isotopes and have different dispersion .In terms of dosage to a human living nearby, coal plants release 100 times the radiotoxicity of nuclear plants. NCRP reports estimated the dot to the population from 1000 MW coal and nuclear plants at 490 person rem/year and 4.8 person rem/year respectively. The Environmental Protection Agency (EPA) estimates an added dose of 0.03 milli-rem per year for living within 50 miles (80 km) of a coal plant and 0.009 milli-rem for a nuclear plant for annually irradiation dosage estimation. Unlike coal-ﬁred or oil-ﬁred generation, nuclear power generation does not directly bring forth any sulfur dioxide, nitrogen oxides, or mercury. So, for the countries where environmental contamination is of grave concern incorporated with cost factor, nuclear can be a better energy option for them.
