Keywords: radioactive contamination, iodine, cesium-137, strontium-90

Abstract: [… The dynamics of radioactive contamination of the affected areas are divided into four periods:

1 – April-July 1986, the condition of radiation contamination was constituted, mainly short-lived radionuclides such as iodine-131, iodine-133, iodine-135, lanthanum-140, barium-140, molybdenum-99, tellurium-132, and neptunium-239; radionuclides with a half-life of 1 year; 2 – 1986-1987., Along with the long-lived radionuclides, were present, in appreciable quantities, radionuclides serenium-144, ruthenium-106, cesium-134, and curium-242; 3 – Since 1988 the radioactive situation has been constituted mainly by radionuclides cesium-137 and strontium-90, and in the evacuation zone; plutonium-238, plutonium-239, plutonium-240 and plutonium-241; 4 – contamination of soil, except those specified in the third period of radionuclides, will be determined by the daughter isotope Pu-241 – americium-241. ..]

Comparative analysis of thyroid diseases incidence in prepubertal children of Kaluga oblast, exposed to iodine-131 in utero and resided in areas with different level of radioactive contamination after the Chernobyl accident

Title: Comparative analysis of thyroid diseases incidence in prepubertal children of Kaluga oblast, exposed to iodine-131 in utero and resided in areas with different level of radioactive contamination after the Chernobyl accident

Author: Gorobets V.F

Reference: Radiation and Risk (Bulletin of the National Radiation and Epidemiological Registry) Year: 2012 Volume: 21 Issue: 4

Keywords: children, in utero exposure to radiation, pollution of territories by iodine-131 and caesium-137, iodine supplementation, thyroid diseases incidence.

Abstract: Incidence of non-cancer thyroid diseases among prepubertal children exposed to radiation from Chernobyl in utero and resided in Zhizdra, Ulyanovo and Khvastovichi rayons of Kaluga oblast with different level of radioactive contamination was studied. It was shown that the rate of thyroid diseases incidence depended on natural iodine insufficiency in the areas of residence and radioiodine dose. The relative contribution of each of these factors can be estimated by difference between the incidence rate in exposed and unexposed children of the same age and the same area of residence.

DOI: http://dx.doi.org/10.1016/0020-708X(70)90148-1

Keywords: radiocontamination, cesium 137, pregnancy

Abstract: In the mature placenta, concns. of stable K and 137Cs were 1.61 g/kg and 22 pCi/kg, resp. In pregnant women, the K content, determined by whole-body counting, followed the accumulation by the fetus, with the amount of 137Cs-remaining approx. constant at 3.4-4.7 nCi/kg. in the last 5 months before delivery. In infants, a linear relation was noted between total K and body weight, with a constant amount of K/kg. The 137Cs body burden was irregular. Doses from 137Cs in Osaka during the last trimester were 0.032, 0.02, and 0.016 millirem to mother, placenta, and fetus, resp., only ~1% of that received from naturally occurring 40K. Thus, the radiation received by the placenta from 137Cs is negligible.

DOI: http://dx.doi.org/10.1016/0020-708X(70)90147-X

Keywords: radiocontamination, environment, cesium 137, strontium 90, pregnancy

Abstract: The determination of cesium 137 and strontium 90 in human placments was carried out in different laboratories in Japan and Canada, in order to standardize the radioassay procedures. Placentas from normal term deliveries were collected and measured for a period of 12–16 months in the Tokyo and Osaka areas in Japan and in the Montreal area in Canada.

Two procedures required the ashing of the entire placenta prior to radioassay. In the Tokyo group, the ashed organ was placed in a two NaI crystal system, in an almost 4π geometry, and the γ radiation was measured. The Osaka group continues the chemical separation of cesium by precipitation with chloroplatinate; the β radiation is then further measured with an anticoincidence system.
