Nuclear Energy

(1)Radiation is energy and particles released from atoms as they undergo internal nuclear changes. (2)The word radiation frightens many people. (3) Yet, you are surrounded by small amount of radiation every day. (4)Radiation comes from color television sets, the earth, and the sun. (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.

(13)At the present time, nuclear power plants provide electric power to many areas of the world. (14)Whether or not the use of nuclear power will increase or decrease will depend on our finding safe methods to dispose of the nuclear wastes.

(15)Many people question the safety of using nuclear energy. (16)There are hazards associated with using nuclear energy. (17)One of them is disposing of nuclear wastes.(18) Nuclear wastes contain radioactive material which can remain dangerous for a million years. (19)To protect people from harmful radiation, these wastes must be stored. (20)Some nuclear wastes are buried in the ground in concrete vaults.(21)However, waste disposal areas must be monitored to make sure there are no leaks in these vaults.

(22)Because of this waste problem and other problems related to nuclear power, some people think the environment is needlessly harmed.
