锆英砂中２２６Ｒａ、２３２Ｔｈ、４０Ｋ的放射性比活度为８２５７．３Ｂｑ／ｋｇ、３６５９．２Ｂｑ／ｋｇ、和９９５．９Ｂｐ／ｋｇ、镭当量平均值为１２９５３．５Ｂｑ／ｋｇ，分别为石煤渣砖和普通主体建材的１３．６倍和７８．８倍。锆英砂原料堆表面的γ、β线外照射剂量当量率之和的最大值和平均值分别为５．２×１０（－２）ｍｓｖ／ｈ和２．２×１０（－２）ｍｓｖ／ｈ，最大值已超过我国职业性放射工作场所的划分限值．地面、墙面瓷砖釉面的总β放射性核素表面密度平均值分别为０．３Ｂｑ／ｃｍ２和０．２８Ｂｑ／ｃｍ２。地面瓷砖釉面的β射线致成人性腺的年附加剂量当量平均值为１．５ｍｓｖ．
The specific activity of 226Ra, 232Th and 40K in zircon sand was 8257.3Bq / kg, 3659.2Bq / kg, and 995.9Bp / kg, and the radium equivalent weight was 12953.5Bq / kg, respectively, And the general main building materials 13.6 times and 78.8 times. The maximum and average of the sum of the equivalent dose of γ and β radiation on the surface of zircon sand raw material pile are 5.2 × 10 (-2) msv / h and 2.2 × 10 (-2) msv / h, the maximum has exceeded the limit of occupational radiation work place in our country. Surface and wall tile glaze total β radionuclide average surface density of 0.3Bq / cm2 and 0.28Bq / cm2. The annual equivalent dose of ground-glazed beta radiation to adult gonads is 1.5msv.
