Effect of X-ray examination regime on radiation doses for patients separate organs

Dependences of tissue doses for lungs, active bone marrow, mammary glands, thyroid, pancreas, liver, kidneys, spleen, stomach, male and female genitals on the electric potential of X-ray tube in main types of X-ray examinations. Tissue doses were determined by thermoluminescent dosimetry with the use of LiF-detectors. Reference man phantom was applied for experiments. It has been established 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 is recommended to apply X-ray radiation detectors with a high sensitivity as well as sparing technology of examination for decreasing radiation exposure of patients. On condition of the constancy of tissue doses the main criterion for a chosen regime is the information rapacity of an X-ray image
