摘要:
花岗岩是地球表层放射性元素主要载体之一,其放射性与岩石酸碱度、形成时代、成因类型等相关,但并非所有花岗岩都具有放射性,仅某个亚属存在放射性超标现象。西部地区某在建花岗岩质隧道围岩与放射性花岗岩亚属具有较大的相似度,且隧址位于可能产生氡气外溢的深大断裂缝,放射性超标的可能性较大。本文结合放射性核素检测、孔内γ测量及氡气监测对隧址区进行了放射性评价,并提出了工程措施建议。
Abstract:
Granite is one of the main carriers of radioactive elements on the Earth’s surface. Its radioactivity is related to pH, formation age, and genetic type of rock, but not all granites are radioactive, and only one subgenus has radioactivity exceeding the standard. The rocks of a granite tunnel under construction in the western China have a great similarity to the subgenus of radioactive granite, and the tunnel is located in a deep fracture that may generate radon gas spillover, so the possibility of exceeding the radioactivity standard is relatively strong. In this paper, radionuclide detection, gamma measurement in the borehole, and radon gas monitoring were combined to evaluate the radioactivity of the tunnel site, and suggestions for engineering measures were put forward.
