摘　　要：使用我国新一代X-γ剂量率测量仪对湖北省9个国控点进行了天然γ辐射空气吸收剂量率的测量,建立了剂量率与剂量当量的数学模型,计算了9个国控点地区人均年有效剂量当量。结果表明,9个国控点地区的剂量率在59.336～141.638 nGy/h,天然γ辐射致公众人均年有效剂量当量为0.390～0.931 mSv;9个国控点地区天然γ辐射均属正常天然本底水平。To measure the natural γ radiation air absorbed does rate of nine country control parts in Hubei province by our national new X-γ dose rate meter and establishing mathematical model of dose rate and dose equivalent to estimate the annual average effective dose equivalent of the people in nine country control parts.The result is that the dose rate of the nine country control parts is between 59.336 to 141.638 nGy/h,and the natural γ radiation lead the annual average effective dose equivalent is between 0.390～0.931 mSv.It concludes the natural γ radiation of the nine country control parts is normal natural background level.
