摘要
衡阳属高氡本底地区,本文选择位于该地区的人防工程进行氡浓度调查.研究表明,在不做密闭处理的情况下,位于衡阳地区的人防工程中平均氡浓度约为55.9~167.3 Bq/m3,低于国际辐射防扩委员会(ICRP)给出的对室内氡浓度干预行动水平的下限建议值:200 Bq/m3.在该通风条件下利用人防工程,可以不考虑氡的防护.人防工程中的氡浓度随着季节变化而变化,春季偏低,秋季偏高.该结果为人防工程平战结合利用时对氡防护有一定的参考意义.
In this paper, the radon concentration of civil air defense shelter was surveyed in Hengyang area,where there is higher background of radon concentration. If civil air defense shelter is not pressure-tight, the average radon concentration is about 55.9 - 167. 3 Bq/m3, lower than the intervened quantity :200 Bq/m3 ,which is given by the international commission on radiological protection (ICRP). Maybe radon protection is not needed with the ventilation of civil air defense shelter like that. The radon concentration of airtight civil air defense shelter change along with the season,which is lower in spring and higher in autumn. The results can be a reference for using civil air defense shelter during the time of peace or war.
