摘　　要：目的评估使用含天然放射性物质的3种布料所致人体的皮肤年当量剂量与年有效剂量。方法首先利用γ能谱仪测量3种布料样品中所含放射性核素的活度。然后利用蒙特卡罗软件建立理论照射模型,基于国际放射防护委员会(ICRP)男性参考体素模型计算器官剂量及有效剂量,从而对人体的皮肤年当量剂量和年有效剂量进行评估。结果在四周包裹和上覆盖的估算模型中,样品质量从135 g至7197 g变化范围内,这些布料所致成年男性参考人皮肤的年当量剂量范围为:155.41~9028.61μSv,一年中的有效剂量范围为:11.91~1234.44μSv。结论含放射性物质的消费品对人体会产生一些影响。Objective To evaluate annual skin equivalent dose and annual effective dose to consumers arising from three types of cloths samples containing naturally occurring radioactive material(NORM).Methods Firstly,measurement of radioactivity in three types of cloths were made withγ-ray spectrometer.And then,theoretical exposure scenarios were simulated with Monte Carlo software to calculate organ dose and effective dose by using ICRP reference voxel male phantom.Finally,annual skin equivalent dose and effective dose to consumers from these cloths samples were evaluated.Results In the wrapped and covered estimation models used in this study,sample mass ranged from 135 to 7197 g,annual skin equivalent dose to consumers from these cloths samples from 155.41 to 9028.61μSv,and annual effective dose from 11.91 to 1234.44μSv.Conclusions NORM-added consumer products would cause some radiation hazard to human body.
