目的:对海洋油气田天线完好与天线破损的对讲机对工人接触微波辐射进行测定研究,为对讲机微波辐射职业卫生管理提供依据。方法:使用已检定的HI2200型射频电磁辐射分析仪,测定天线完好与天线破损的对讲机、在低频率段和高频率段的频率段下,工人接触的微波辐射强度和剂量。结果:天线完好的对讲机在低频率段、高频率段两种频率段下发射状态的工人短时间接触功率密度最大值分别为18.3μW/cm^(2)、99.2μW/cm^(2),工人日接触剂量分别为9.1μW.h/cm^(2)、49.6μW.h/cm^(2);天线破损的对讲机在低频率段、高频率段两种频率段下发射状态的工人短时间接触功率密度最大值分别为1521.5μW/cm^(2)、3044.9μW/cm^(2),工人日接触剂量分别为760.7μW/cm^(2)、1522.4μW/cm^(2)。结论:海洋油气田对讲机天线完好时工人接触的微波辐射短时间接触功率密度和日接触剂量均符合国家标准,对讲机天线破损时工人接触的微波辐射短时间接触功率密度符合国家标准、日接触剂量超过国家标准。

[Objective]To measure the microwave of workers,exposed to interphone with intact or damaged antenna in offshore oil and gas fields,provide the basis for the occupational health management of interphone microwave.[Methods]The microwave intensity and dose of workers,exposed to interphone with intact antenna and damaged antenna and in the frequency band of low frequency and high frequency were measured by the certified HI2200 radio frequency electromagnetic radiation analyzer.[Results]The maximum short-time exposure power density of workers with intact antenna interphone was 18.3μW/cm^(2) and 99.2μW/cm^(2) in low frequency and high frequency,respectively,while the daily exposure dose of workers was 9.1μW.h/cm^(2) and 49.6μW.h/cm^(2) respectively.And the maximum short-time exposure power density of workers with damaged antenna interphone in low frequency and high frenquency was 1521.5μW/cm^(2) and 3044.9μW/cm^(2),respectively,while the daily exposure dose of workers was 760.7μW.h/cm^(2) and 1522.4μW.h/cm^(2) respectively.[Conclusion]The short-time exposure power density and daily exposure dose of workers with intact antenna interphone in offshore oil and gas fields meet the National Health Standard for microwave in workplace(The Standard),and the short-time exposure power density of workers with damaged antenna interphone in offshore oil and gas fields meets The Standard while the daily exposure dose exceeds The Standard.
