某电信研发企业工作场所微波辐射暴露的测量与评价

Microwave radiation level in workplaces in Telecom R&D enterprises

目的了解电信研发企业职业人群微波电磁辐射职业暴露状况。方法以3家电信研发企业不同工作区域的各微波接触岗位为调查对象,对其微波辐射功率密度进行调查分析。结果 3家企业共检测12个工作区域的115个作业岗位,188个检测点,结果显示各区域间的微波辐射强度存在明显差异,其中发射区13个岗位中有2个岗位微波辐射强度超过国家标准,其余岗位微波辐射强度均符合国家职业卫生标准。结论电信研发企业的发射工作区存在较强的微波辐射暴露,应采取屏蔽等综合措施控制其职业危害。

Objective To observe the occupational exposure level of microwave radiation in workplaces in Telecom R D enterprises.Methods 3 R D enterprises on mobile phones and related telecommunications were selected as study objects.The microwave radiation density were measured in different workplaces.Results Totally 118 work-sites were measured among 115 workplaces of 12 different work areas.The results showed that the microwave radiation intensities varied greatly in different work-sites.However,only in the emission area,there were 2 sites where microwave radiation intensities were higher than the national standards among 13 sites.Conclusion There was relatively strong exposure to microwave radiation in the emission areas in telecom R D enterprises,the shielding and other comprehensive measures should be taken to control its occupational hazards.
