RESUMO
Internal and total irradiation doses for the population of Zugdidi, Khobi, Tsalenjikha districts (Samegrelo region, Georgia) have been defined and hygienically assessed; preventive measures have also been proposed for its reduction. Internal irradiation dose for the population of Samegrelo region was identified as 2.26 mSv/y, total irradiation dose -- 3.31 mSv/y, i.e. relatively increased. To reduce the total irradiation dose of the population apart from the need to prohibit use of high activity water for drinking and to provide population with new sources of low activity water, it is necessary to control and minimize doses caused by the artificial irradiation; this should primarily happen by means of regulation of medical radiological procedures and rational use of fertilizers with K-40 content.

Study of certain immune status indicators of medical roentgenologists has detected certain immunodeficiency associated with exposure to low doses of ionizing radiation. The number of T-lymphocytes has been noticed to be reduced, while the degree of reduction increases with age, duration of work in the sphere of radiation, and the value of the individual dose of radiation within a year. B-lymphocytes number is susceptible to changes in a smaller degree.

The number of T- and B-lymphocytes of the peripheral blood was studied in 59 medical radiologists. A decrease in the number of T-lymphocytes was noted, its degree being associated with an individual annual dose of irradiation, the period of contact with radiation and age. The number of B-lymphocytes was changed to a lesser degree. It is assumed that a previously reported decrease in the body resistance to environmental hazards depends, to a certain extent, on immunodeficiency detected in this work as well as on the deficiency of metabolism of C and B1 vitamins reported earlier.
