title: [Radiation exposure of the patient and personnel during punctures controlled by roentgenotelevision and computed tomography].
abstract: Determined by means of thermoluminescent dosimetry radiation exposure to a patient from punctures controlled by two-projection x-ray and TV was, on an average, 0.0176 Gy +/- 18%, and when controlled by CT it was 0.048 Gy +/- 22% which was comparable with dose exposure of 2 x-ray films in the first case and of 5 x-ray films in the second case. Assessment of radiation exposure to a physician was based on the ratio of single and maximum permissible annual equivalent doses. This ratio of doses to the gonads limited the permissible number of punctures controlled by two-projection x-ray and TV up to 80 per year and that of punctures controlled by CT up to 150 per year. Individual dosimetric control is obligatory for physicians regularly engaged in this type of investigations.
