[Immune status indices of medical radiologists].

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.
