It has been well known that nuclear power plant and coal-fired power plant release some amount of radioactive materials during their normal operations. The purpose of this study was to compare radiation exposure doses to the public as a consequence of airborne effluents released from nuclear and coal-fired power plants under the normal operation. NRCDose3 was used to estimate radiation exposure doses to the public from gaseous effluents of nuclear power plant during its normal operation while CAP88-PC was used to calculate doses to the public living around coal-fired power plant. The results showed that radiation exposure doses from nuclear power plant were less than those from coal-fired power plant and regulatory annual limits. Effective dose by external exposure, skin equivalent dose, and organ equivalent dose from gaseous effluents of nuclear power plant were 2.93 × 10⁻⁴ mSv/y, 2.90 × 10⁻³ mSv/y, and 1.78 × 10⁻² mSv/y, respectively. On the contrary, the corresponding effective dose by external exposure, external skin dose, and organ dose from coal-fired power plant were 1.13 × 10⁻² mSv/y, 5.33 × 10⁻² mSv/y, and 1.17 × 10⁻¹ mSv/y, respectively.

核电厂和燃煤电厂排放的放射性空气对公共健康的影响

众所周知，核电厂和燃煤电厂在其正常运行期间会释放一些放射性物质。这项研究的目的是比较正常运行情况下从核电厂和燃煤电厂释放的空气污染物排放给公众的辐射剂量。NRCDose3用于估算核电厂正常运行期间其气态排放物对公众的辐射暴露剂量，而CAP88-PC用于计算燃煤电厂周围公众的辐射剂量。结果表明，核电厂的辐射暴露剂量低于燃煤电厂的辐射暴露剂量和监管年度限制。外用有效剂量，皮肤当量剂量，^-4  mSv / y，2.90×10 ^-3  mSv / y和1.78×10 ^-2  mSv / y。相反，燃煤电厂通过外部暴露，外部皮肤剂量和器官剂量产生的相应有效剂量分别为1.13×10 ^-2  mSv / y，5.33×10 ^-2  mSv / y和1.17×10 ^-1  mSv / y。
