| Abstract:: |
| Objective To evaluate the upper limit of individual dose to the people of occupational exposure(medical doctors) and appraise radiation safety on using prostate hyperplasia applicators. Methods The radiation dose(directional and ambient dose equivalent)around the source of the prostate hyperplasia had been determined with radiation protection instruments.According to inquired situation of clinical application of prostate hyperplasia applicators in hospitals and measured radiation dose in clinical probation period, the upper limit of individual dose of midical doctors had been evaluated as well. Results The upper limit of individual dose per person_course are 6.0 μSv for arethra_type and 4.5 μSv for rectum_type,respectively. Conclusions Under the normal conditions,the radiation safety can be ensured when operating the prostate hyperplasia applicators. |
