Kebocoran radioaktif yang boleh membawa maut.

TOKYO - Ketika pihak berkuasa Jepun melaporkan lebih 80,000 orang dikhuatiri terkorban akibat gempa bumi dan tsunami terburuk dalam tempoh 140 tahun kelmarin, penduduk negara matahari terbit itu kini berdepan pula dengan kebocoran radioaktif yang boleh membawa maut.

Health risks could include specific types of cancers, stillbirths and acute radiation syndrome if a full meltdown occurs, experts said. Of particular concern are three chemicals that can be released from nuclear facilities that mimic substances the body naturally uses, such as iodine and potassium. These chemicals are radioactive Iodine, Cesium and Strontium-90, said Dr. Chesser.

Problems to the thyroid are of particular concern. The thyroid gland doesn't differentiate between radioactive iodine and the normal kind, which it uses to produce hormones and function normally. Adolescents, whose bodies are quickly growing, are at particular risk. In addition, the effects can be long term: Dr. Chesser said that following the nuclear explosion in Chernobyl, thyroid cancers started to significantly increase only seven years after exposure. Dr. Chesser also recommended that people stay indoors as much as possible.

Other health risks include bone cancer and compromised immune systems if the poisonous particles damage bone marrow. Fetuses and children are particularly susceptible to these risks since their immune systems are weaker, as are those of elderly people, experts said. Birth defects can arise after radiation exposure if the fetus is exposed to the toxic substances.

In an extreme case, people exposed to very high levels of radiation, such as after a nuclear bomb like the one dropped on Hiroshima, can suffer from radiation sickness, or acute radiation syndrome, said Mr. Mangano. Symptoms include fever, nausea, vomiting and skin rashes.

~Semoga tak terjadi la perkara buruk lagi ye.. Dah la kena gempa bumi, kalau kebocoran radioaktif pula memang membimbangkan. Nanti jadi macam Tragedi Hiroshima ke dua pula..
