INVESTIGATION OF BIOKINETIC PECULIARITIES OF STRONTIUM-90 METABOLISM MODEL AND POSSIBILITY OF AN ESTIMATION OF RADIONUCLIDE INTAKE LEVEL BASING ON THE RESULTS OF THE MEASUREMENTS OF ACTIVITY IN URINE
An article presents the results of the substantiation of possibility of the use of age-dependent biokinetic model of 90Sr in a human body for estimation of the average levels of a daily intake with a diet by means of measurements of radionuclide activity in a daily urine sample. It is shown that for...

| description | An article presents the results of the substantiation of possibility of the use of age-dependent biokinetic model of 90Sr in a human body for estimation of the average levels of a daily intake with a diet by means of measurements of radionuclide activity in a daily urine sample. It is shown that for persons of different age groups in a case of chronic intake of 90Sr the rate of excretion with urine, basically, reflect by the temporary depots of radionuclide fixation in soft tissues and on a surface of the bone, and depends slightly on accumulation of radionuclide in the whole skeleton. Besides, temporary depots of radionuclide fixation fulfill the function of averaging of radionuclide intake in a case of daily intake levels, randomly timely distributed. |
