Iodine-129 in rabbit thyroids near a nuclear fuel reprocessing plant in Idaho.

Thyroids were collected from rabbits on and near the Idaho National Engineering Laboratory (INEL) Site in southeastern Idaho and analyzed for 129I and stable iodine, 127I. The 129I/127I atom ratios in rabbits collected on the INEL site were larger than ratios in rabbits from a control area. Maximum 129I/127I atom ratios (9.1 x 10(-4)) occurred near the Idaho Chemical Processing Plant (ICPP). Based on rabbit thyroid concentrations, the 129I appeared to be deposited primarily in the direction of the predominant winds from the ICPP, northeast and southwest. Dose rates from the 129I to thyroids of INEL rabbits varied from 0.1 to 260 muGy/y (0.01 to 26 mrad/y). Iodine-129 atmospheric releases from the ICPP appeared to have increased the 129I/127I atom ratios on and near the INEL site.

The accuracy of some simple models for predicting particulate interception and retention in agricultural systems.

The accuracy of three radionuclide transfer models for predicting the interception and retention of airborne particles by agricultural crops was tested using Pu-bearing aerosols released to the atmosphere from nuclear fuel facilities on the U.S. Department of Energy's Savannah River Plant, near Aiken, SC. The models evaluated were: 1) NRC, the model defined in U.S. Nuclear Regulatory Guide 1.109; 2) FOOD, a model similar to the NRC model that also predicts concentrations in grains; and 3) AGNS, a model developed from the NRC model for the southeastern United States. Plutonium concentrations in vegetation and grain were predicted from measured deposition rates and compared to concentrations observed in the field. Crops included wheat, soybeans, corn and cabbage. Although predictions of the three models differed by less than a factor of 4, they showed different abilities to predict concentrations observed in the field. The NRC and FOOD models consistently underpredicted the observed Pu concentrations for vegetation. The AGNS model was a more accurate predictor of Pu concentrations for vegetation. Both the FOOD and AGNS models accurately predicted the Pu concentrations for grains.

Radioiodine fallout over the Midwest in May.

High concentrations of radioiodine in milk, found preferentially over the midwestern United States after atmospheric nuclear tests in May 1962, 1965, and 1966, can best be explained by high-reaching intense thunderstorms that scavenge passing radioactivity from the upper troposphere and lower stratosphere.

[Actual measurements following the Chernobyl reactor accident].

The principles of radiation protection for the population in Austria as applied in context with the catastrophic releases of radioactivity from the Chernobyl nuclear power reactor are presented. The main results of the first air filter analyses, which allowed an identification of the problem are discussed. The following measurements show, that after radioactive decay of Iodine-131, the main route for intake of Cäsium-137 will be ingestion with the foodstuffs over a longer period. Dose estimations give 80 to 100 mrem/year (0.8 to 1.0 mSv/a) effective committed dose equivalent caused by the nuclear accident.
