Release and Movement of Radionuclides in Soils Contaminated with Fallout Material from an Underground Thermonuclear Detonation.

چکیده
Fallout material from an underground thermonuclear detonation was analyzed to determine the presence of several longer lived radionuclides. The following radionuclides were identified: Zr95-Nb95, Rul03, Rul06Rhl06, 1131, Csl37-Bal37, Bal40-Lal4O, Cel4l, Cel44-Prl44, Sc46. Mn54, Y88, Rhl02, W181., W185, and W188-ReI88. Radiotungsten contributed the major fraction of the total activity. In suspension studies, chelating agents as compared to water, generally increased the amount of soluble radionuclides, but the effect was small. The effect of water and a chelating agent on the movement of radionuclides in soil columns were also studied.

Soil-plant-man is recognized as a major pathway for the transfer of radionuclides to human beings [(Safety Series, No. 57 (IAEA 1982)]. The radioactivity of environmental samples from sites and products suspected of contamination must be investigated before free access to them is given to the public (Owono 2010). Radionuclides in soils are frequently transferred to different plant tissues by di...
