摘　　要：本文用硫代硫酸钠浸渍炭法测定医院同位素室空气中￣（１３１）Ⅰ浓度，采￣（１３１）Ⅰ效率为９８．８～９９．７％。用ＬｉＦ（Ｍｇ、Ｃｕ、Ｐ）热释光剂量计测定外照射剂量。结果表明：工作人员外照射剂量当量在０．１～０．５ｍＳＶ占６４％，３．０～５．０ｍＳＶ仅占６．６％；吸入￣（１３１）Ⅰ年有效剂量当量最大约０．３ｍＳＶ．ａ￣（－１）；１０所医院同位素室桌面、地面β污染均未超过导出限值；用￣（１３１）Ⅰ治疗甲亢患者￣（１３１）Ⅰ大部分随尿、粪便排出，仅有少量随唾液、汗水、呼出气排出。he methods of charooal immersed Na￣2S￣2O_3 with 98.8-99.7%samplingefficiency were used to determine the ￣(131)Ⅰ of air in places of nuclear me-dicine work, LiF(Mg,Cu, P) TLD were also used to measure the extern-al dosage,whicli showed the equivalent doses per year of 0.1～0.5mSv in65%,of 3.0～5.0mSv in 6.6% for 106 cases. Equivalent doses per yearfrom inhalation did not exceed 0.32mSv,β-activity level on table andsurfaces iN 10 hospital were lower than limits of Basic Health Standardsfor Radiological Protection GB 4792-84.The great part of ￣(131)Ⅰ activityexcreted from hyperthyroidism patients was in the urine and fecal samples,a little in saliva,sweat and expired air.
