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.
通过热释光剂量测定法确定,在双投影X射线和电视控制下进行穿刺时患者所受的辐射暴露平均为0.0176戈瑞±18%,而在CT控制下则为0.048戈瑞±22%,这与第一种情况下2张X光片以及第二种情况下5张X光片的剂量暴露相当。对医生辐射暴露的评估基于单次与年度最大允许当量剂量的比值。这种性腺剂量比值将双投影X射线和电视控制下穿刺的允许次数限制在每年80次以内,CT控制下穿刺的允许次数限制在每年150次以内。对于经常从事这类检查的医生,个人剂量测定控制是必须的。
