(5)The effects of small amount of radiation are not completely known. (6)However, exposure to large amounts of radiation is known to cause birth defects and cancer in humans.
(7)Nuclear energy is the conversion of energy released as radiation to electrical energy. (8)In a time when energy sources are being used up, nuclear energy is a possible major source of energy production. (9)Nuclear fission, or the splitting of atoms, releases heat which is used to produce steam from water. (10)The steam turns an electric motor which in turn turns a generator. (11)The generator produces electricity. (12)This process takes place in nuclear power plants.
