چکیده انگلیسی
The International Commission on Radiological Protection (ICRP) assumes that cesium and potassium are homogenously distributed throughout the whole body of an organism. However, the presented results show that there is a non-uniform distribution of 137Cs and 40K in different skeletal bones and their adherent tissues of a dairy cattle. We found that activity concentrations of 137Cs and 40K varied up to a factor 2.5 in different components of the ribs. The minimum values of 137Cs and 40K in the ribs were 29.9 and 21 Bq kgâ1 fresh mass for trabecular bone in the vertebral half of asternal ribs, and the maximum values 332 and 132 Bq kgâ1 fresh mass for a mixed sample composed of a cartilaginous tissue layer and parts of the perichondrium, both originating from asternal costal cartilages, respectively.
