【摘要】 目的了解核医学人员的受照剂量水平及防护中的薄弱环节。方法采用热释光剂量计（Thermoluminescent Dosimeter,TLD）和光致发光剂量计（Optically Stimulated Luminescence,OSL）对核医学人员佩戴的H_p（10）、H_p（3）和H_p（0.07）剂量计进行月受照剂量监测,并以此评估核医学职业人员全身有效剂量、眼晶体当量剂量和手部当量剂量;利用COMO170表面污染仪对核医学人员的体表进行表面污染监测。结果 ¹⁸F注射人员的全身有效剂量和眼晶体剂量值最高,分别为0.34和0.35 mSv,回旋制药人员手部剂量值最高,为48.2 mSv;部分人员核素操作后手部和工作服有放射性核素污染。结论 ¹⁸F操作人员应加强自身防护,手部剂量应引起重视。更多还原

【Abstract】 Objective To investigate the dose received by the professional staff and the weak links in protection management in nuclear medicine departments. Methods Thermoluminescent dosimeter（ TLD） and optically stimulated luminescence（OSL） were used to measure radiation dose received by the professional staff including H_p（10）,H_p（3） and H_p（0. 07）,then to assess the whole body effective dose,eye lens equivalent dose and hand equivalent dose. A COMO170 surface contamination monitor was employed to test the operator’s body surface. Results The ¹⁸F drug injectors exhibited the maximum effective dose of 0. 34 mSv and the maximum eye lens dose of 0. 35 m Sv. The Cyclotron pharmaceutical operators gave the maximum hand skin dose of 48. 2 mSv. The surface contamination was occasionally found at the hand or the clothes after operation. Conclusion Self-protection should be strengthened for ¹⁸F operators,and be paid enough attention to the radiation exposure of hand.更多还原
