Assessment of occupational exposure and individual radiosensitivity in people exposed to radiation using methods of physical and biological dosimetry

This paper examined people professionally in contact with sources of ionizing radiation.The incidence of chromosomal aberrations, the radionuclide content in the urine of the radiochemical method and calculation of internal doses based on the results of direct measurement of the concentration of incorporated radionuclides ¹³⁷Cs and ²⁴¹Am using human radiation spectrometer (HRS). According to the results of physical and biological dosimetry identified individual cumulative doses and the ratio defined cohort surveyed by radiosensitivity Key words: chromosomal aberrations, physical methods of dosimetry, radiation sensitivity, ionizing radiation, biodosimetry
