Abstract

The relationship between 90Sr accumulation in the skeleton after single injection and the resulting dose load on bone surfaces was studied in laboratory mice. Radiation doses were measured by a thermoluminescent method. A positive correlation was revealed between the surface dose rate on the skull and mandible and 90Sr specific radioactivity in these bones. The possibility to calculate 90Sr incorporation into the bone tissue from dosimetric data was evaluated as an analytical approach allowing preservation of the bone material for subsequent studies. Conversion coefficients relating surface doses to 90Sr specific radioactivity in bones were calculated. However, their values have to be specifically defined for cases of chronic 90Sr input and with regard to bone anatomy and species-specific and ecological features of test animals.
