摘 要:During 1991-1993, the radioactivity levels of the bone-coal mines were investigated in Hubei, Hunan, Ji-angxi, Zhejiang and Anhui Provinces, respectively, where the reserve of bone-coal is about 90% of our country’s total reserve. The annual additional collective dose equivalent within 80km evaluated region of bone-coal power stations in Nijiangkou and Anren is 1.7 and 1.9 man·mSv, respectively, and that of Zhuantanyan bone-coal shaft is 1.4 man·mSv. The collective dose equivalent caused by bone-coal cinder brick produced for 25 years in the five prov-inces is 1.6×105 man Sv.
