Nuclear radiation caused cancer and Infertility
On Nuclear Power cleavage reaction of atomic nuclei in a nuclear reactor. This reaction produces some isotopes such as Xenon-133, krypton-85, and Iodine-131 with a release of energy. This decay process also produces radioactive substances such as alpha rays, beta and gamma. Among the three most dangerous gamma radiation. Type of radioisotopes commonly detected in gamma radiation is cobalt-60, cesium-137, cadmium-109, sodium-22, manganese-54, barium-133 and cobalt-57.
Leakage of nuclear reactors can release radioactive substances into the environment. The case of the 1996 Chernobyl release of radioactive material is great especially radioisotopes of cesium and iodine that contaminate water, food, and air. Report the impact of the explosion at Chernobyl released World Health Organization (WHO) declared around 4000 thyroid cancer cases occur in Belarus in 1990-2002, other than that reported increased cases of leukemia (blood cancer).
Chairman of the Nuclear Energy Supervisory Agency (Bapeten) As Natio Lasman said, a person can be exposed to radioactive substances on the outside and inside the body. Because the radioactive substance can be entered during breathing, eating, drinking, or through wounds. Contamination can occur in sea water used as coolant. Radioactive particles can be ingested fish and will go into the human body which consume fish. Radioactive particles could be flown wind and contaminate soil, water and air around.
Radiologist who is also Chairman of the Executive Board of the Indonesian Doctors Association (IDI), Prijo Sidipratomo say, so get into the body, radioactive isotopes will be distributed throughout the body. Most settle in the organ or tissue, partly out through the urine, feces, and sweat. Radioactive contaminants can accumulate in body organs according to the nature of physics and chemistry. If the body exposed to doses of 350-450 rem in quick time, there is a 50% risk of death within 30 days. Dose of 100 rem in a long time cause cell damage that can not be restored. Prijo say, cell damage can impair organ function. Depending on which part of contaminated radioactive substances. If exposed to the gonads (testicles or ovaries) may occur sterility. Moreover, it can happen mutation that causes cancer cells to organs and blood. The organs that are sensitive to radiation exposure is the thyroid gland, intestines, kidneys, spleen and bone marrow. Radioactive exposure in pregnant women may interfere with fetal growth, ie irregularities in the process of organ growth. Exposure in children was also dangerous since the body cells more vulnerable children. In addition, the child's body area is smaller than adults, so even though the amount of exposure to the same but the dose becomes greater.
To reduce the radioactive substance which has entered the body's effort to reduce absorption in the digestive tract, inhibiting the deposition in the organs of the body, dilution, change the chemical properties of materials and the use of chelate techniques.
