| 摘 要： | 通过在拟开掘隧道沿线的专门勘探平洞和煤矿巷道中进行的γ辐射剂量率(225组数据)和环境氡浓度(96个数据)测量,评价和研究该区未来隧道放射性辐射环境。这些平洞和巷道均穿越了(或低于)拟开掘隧洞的底部,基本上揭露了比选隧洞可能穿越的地层岩性。结果表明,在该区煤系地层和侏罗系砂岩交接带可能会出现环境γ辐射照射剂量超标现象,在上述交接带以及含土碎石分布区,有可能出现环境氡浓度超标现象。在选线和施工过程中应引起重视。 |

| Abstract: | In-situ measurements were mainly performed at 6 test tunnels and 2 coal mine tunnels along the possible long tunnel.Totally 225 sets of gamma-radiation dose rate and 96 of radon emanation data were obtained.Based on the data the environmental terrestrial radiation was evaluated.The results show that gamma-radiation dose might be higher than the national standard at the connective belts of coal seams and sandstone of Jurassic age,and radon emanation anomaly probably occur at the belts mentioned above and the gravel soil area.It is suggested that special attention should be paid to those sites during the selection of long tunnel lines. |
