我们对24例受低剂量外照射的石油测井人员血清中的SOD-1进行检测,以期为对其进行放射卫生评价提供依据。 材料和方法 44例受低剂量外照射的人员,全部为男性。年龄18～33岁,平均26.5±4.5岁。接触射线的时间为3个月～11年,平均为3.77±3.65年。所接触的放射源主要是2～18Ci的钴-60γ源和200mCi的中子源。虽然每次操作源的时间不超过1min,但源是不加任何保护的裸源。而且每天操作次数较多。不过,该组人员的外照射剂量均未超过国家标准。对照组为从未接触射线的正常成人53例,年龄16～55岁,平均34.5±12.0岁。所有对象清晨空腹静脉采血3ml,分离血清后,去除溶血标本。采用上海放射免疫分析技术研究所提供的SOD-1 RIA kit检测血清SOD含量。结果全部为正态分布,且方差均齐,以(?)±S表示,用t检验处理。测量仪器为262厂生产的FJ-2008Pγ免疫计数器。
We tested 24 cases of SOD-1 in the serum of oil well logging staff exposed to low doses of external radiation, in order to provide a basis for their radiological health evaluation. Materials and Methods 44 cases of low-dose external exposure personnel, all male. Aged 18 to 33 years old, with an average of 26.5 ± 4.5 years. Exposure to the ray of time for 3 months to 11 years, an average of 3.77 ± 3.65 years. The radioactive sources contacted were mainly 2 ~ 18Ci cobalt-60γ source and 200mCi neutron source. Although each operation source time does not exceed 1min, but the source is naked without any protection. And more daily operations. However, the group’s external dose of radiation did not exceed the national standard. The control group of 53 normal adults who had never been exposed to radiation, aged from 16 to 55 years, with an average of 34.5 ± 12.0 years. All subjects fasting venous blood 3ml, after the separation of serum, removal of hemolysis specimens. SOD-1 RIA kit provided by Shanghai Institute of Radioimmunoassay was used to detect serum SOD. The results are all normal distribution, and the variance is homogeneous, with (?) S said t test. Measuring instrument for the FJ-2008Pγ immunization counter 262 plant.
