[Tissue irradiation doses in roentgenologic examinations of thoracic organs]. / Tkanevye dozy oblucheniia pri rentgenologicheskikh issledovaniiakh organov grudnoi polosti.

The paper is concerned with the results of experimental studies on the equivalent doses of irradiation of 11 organs and tissues by which one can calculate effective equivalent doses per study. Calculation were done on an anthropomorphous phantom of "conventional" man with the help of a thermoluminescent dosimetric system based on lithium fluoride. Equivalent doses were evaluated by the mean calculated value. The tabulated results make it possible to determine equivalent doses.

[Effect of the schedule of x-ray examinations on the radiation dosage of specific organs in patients]. / Vliianie rezhima provedeniia rentgenologicheskogo issledovaniia na dozy oblucheniia otdel'nykh organov patsienta.

It has been established on the basis of experimental dosimetric studies that during x-ray studies tissue doses of the irradiation of vital organs depend very little on the voltage of the x-ray tube in the range of 80-120 kV. It necessitates the use of x-ray radiation detectors with a high sensitivity as well as sparing technology of examination to decrease radiation exposure of patients. On condition of the constancy of tissue doses the main criterion for a chosen schedule is the informative value of an x-ray image.
