A preliminary investigation on internal exposure dose of artificial radionuclides in nuclear medicine staff
Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 3
Abstract
ObjectiveTo tentatively understand the status of radioactive contamination in nuclear medicine personnel.MethodsA total of 34 radiation staff engaged in nuclear medicine diagnosis and treatment were selected from two hospitals in Shanghai as the survey subjects.Among the 34 medical staffï¼ 8 were nuclear medicine doctorsï¼ 14 were nuclear medicine technicians and 12 were nuclear medicine nurses. After surface contamination monitoring was first carried out to confirm that they had no surface radioactivity contaminationï¼ whole body scanning was performed with a whole body counter to determine whether they were internally contaminated with artificial radionuclides.ResultsThe α surface contamination was not detected in the nuclear medical staff. The β surface contamination of the nuclear medicine doctorsï¼ technicians and nurses was ï¼13.8±0.8ï¼ï¼ ï¼14.1±0.8ï¼ and ï¼14.0±0.7ï¼ times per secondï¼ respectively. There were 2ï¼ 2ï¼ and 4 nuclear medicine doctors who were contaminated with 18Fï¼ 99mTc and 131Iï¼ 3ï¼ 5ï¼ and 2 nuclear medicine technicians who were contaminated with 18Fï¼ 99mTc and 131Iï¼ and 6ï¼ 8ï¼ and 5 nuclear medicine nurses who were contaminated with 18Fï¼ 99mTc and 131Iï¼ respectively. The 18F activity of nuclear medicine technicians was 1 997â9 401 Bqï¼ and the 99mTc activity of nuclear medicine technicians and nurses was 3 699â18 692 and 652â388 22 Bqï¼ respectively. One nuclear medicine nurse had a 99mTc activity of 35 389 Bq. According to the preliminary estimation of 131I internal irradiation doseï¼ the maximum committed effective dose of nuclear medicine doctorsï¼ technicians and nurses could reach 0.370ï¼ 0.018 and 0.584 mSvï¼ respectively.ConclusionThe nuclear medicine staff are exposed to radioactive contaminationï¼ and it is important to monitor and evaluate their internal radiation doses.
