Measures of thyroid function among Belarusian children and adolescents exposed to iodine-131
from the accident at the Chernobyl nuclear plant.
([.sup.131.I]) is widely used for the treatment of thyroid-related diseases.
decays into a stable atom of xenon with primary beta radiation of 606 keV and primary gamma radiation of 364 keV.
During the Green Run, Air Force planes measured the deposits of iodine-131
on ground vegetation within a 200- by 40-mile plume that stretched from The Dalles to Spokane.
The thyroid's powerful ability to concentrate iodine is what causes trouble when you come into contact with radioactive iodine-131
. (14) That radioisotope is a powerful emitter of beta-radiation with a half-life of 8 days.
"The IAEA believes the current trace levels of iodine-131
that have been measured do not pose a public health risk and are not caused by the Fukushima Daiichi nuclear accident in Japan," dpa quoted the Vienna-based agency as saying.
It did not specify if the contamination was from iodine-131
or caesium-137, the official safety limits for which are 2,000 Bequerel per kilogramme and 500 Bequerel per kilogramme respectively.
And campaigners have demanded a probe by health chiefs on the eve of the 25th anniversary of the catastrophe Particles of highly radioactive iodine-131
- which can cause cancer as the body stores it in the thyroid gland in the neck - were scattered across Scotland by rain showers after the Soviet nuclear plant disaster.
The partial meltdown of Fukushima, in contrast, released only five isotopes measurable by the Seattle team: iodine-131
, iodine-132, tellurium-132, cesium-134 and cesium-137.
According to South Korean News Agency Yonhap, Korea Institute of Nuclear Safety (KINS) reported Minuscule traces of iodine-131
were found in the seven areas including Seoul with traces of cesium-134 and cesium-137 was detected in four areas.
The Food Safety Authority of Ireland said tests carried out by the national radiological institute had discovered trace levels of iodine-131
, a radioactive isotope, in three individual samples.
