The International Atomic Energy Agency (IAEA) confirmed the presence of radioactive iodine in the Fukushima area, the region where the plant is severely damaged by the devastating tsunami that followed the earthquake of 11 March. The UN body said the contamination was confirmed by the Japanese Ministry of Health, Labour and Welfare, and, "according to the latest data, it is contaminated products found in the measurement tasks performed between 16 and March 18.
"To date, no other radioactive isotope (and iodine) have shown an increase in food analysis about Fukushima." The agency notes that, although the radioactive iodine has a short life of about 8 days and then its radioactivity decays naturally within weeks, there is a short-term risk to human health if absorbed by the body.
Ingestion may lead to an accumulation in the body and affect the thyroid, a hazard that affects mostly children and youth. On the other hand, the IAEA said in Vienna that the UV radiation reaching Tokyo are "below the limit" from which are harmful to human health. "IAEA spokesman, Andrew Graham, said in the daily press briefing measurements made in Tokyo agency team revealed slight increases of radioactivity, but at levels that do not threaten health.
The spokesman said that there were no radioactive isotopes of iodine (iodine-131) or cesium (cesium-137) and the Fukushima nuclear plant, radiation remains high and no major changes. Andrew also noted that so far it is unknown if the pumps work to cool the reactors at the Fukushima nuclear plant after power is restored.
As a precautionary measure, the Japanese authorities on the 16th gave the order to distribute iodine tablets and syrup nonradioactive the population evacuated from the area of 20 km radius around the plant Fukushima. -Ingested radioactive particles can irradiate the body from the inside for a few weeks (iodine 131) or up to two years (cesium 137).
Iodine-131 loses half its radioactivity every eight days. As the cesium 137, is every 30 years. But the body gets rid of them more quickly eliminated in urine and faeces. Iodine 131 can be set mostly in the thyroid gland instead of stable iodine, which has mainly a risk for children. The tablets that saturate the thyroid iodine stable prevent radioactive iodine it is fixed.
Health authorities are responsible for recommending to take these pills in case of danger confirmado. "The energy of ionizing radiation can damage DNA in cells of the body. If the injuries are not too important, that DNA can be repaired and the cell then beget normal daughter cells. But a service may facilitate the development of cancer much later.
