Abstrakt: Using the gamma-spectrometric method we found that the radioactive isotope 125I, when entering the body of a rat, actively accumulated not only in the thyroid gland, but also in the bones. The 125I activity level in bone tissue was quite comparable to that of 90Sr, for which bone tissue is critical. Although the specific radioactivity of 125I in bones is significantly lower than in the thyroid gland, the great mass of bone tissue in the skeleton underlies the high level of radiation to the red bone marrow. 131I, which is not only a gamma but also a beta emitter and a leading radionuclide in dose formation during the first days after an accident, is also released to the environment from nuclear power facilities, along with the accidental release of 125I. In this regard, the results obtained for 125I are quite comparable to data on 131I in terms of the identical nature of their distribution in animals and humans. [ABSTRACT FROM AUTHOR]
