This dissertation discussed the identification criterion of associated mine,it suggests that based on the calculation formula of internal radiation index IRa=ARa/400 and external radiation exposure index Iγ=ARa/330+ATh/260+AK/3800,when it is satisfied IRa≥1 or Iγ≥2,then it is identified as associated mine。
论文探讨了伴生矿判定标准,建议按照内照射指数IRa=ARa/400,外照射指数Iγ=ARa/330+ATh/260+AK/3800计算,满足IRa≥1或Iγ≥2任何一个条件均确定为伴生矿。
