The geographic distribution, γ-radiation level and specific activity of radionuclides of the bone-coal mines in Zhejiang Province were reported. The weighted average of γ-radiation dose rate of the bone-coal mines is 566 nGy/h for 107 main bone-coal mines. The weighted mean activity of ²³⁸U, ²²⁶Ra, ²³²Th and ⁴⁰K in the samples are 949, 918, 34 and 554 Bq/kg for 171 samples of bone-coal, respectively.
