Abstract Objective To investigate the radioactivive level of water body in collapse pit caused by mining, develop and use the resource reasonably, the water body in collapse pit was studied in detail.Methods radioactivity analysis was made according to the national standard.Results The average activity concentration of gross-alpha in the water was 4.99×10-2Bq/L.The average activity concentrations of gross-beta was 4.30×10-1Bq/L.The average activity concentrations of Ra was 1.28×10-2Bq/L.The results show that the average activity concentrations of gross-alpha, gross-beta and Ra were higher significantly than those in the groundwater and tap water.Conclusion The radioactive mornitoring of water body should be paid attention to when the water in collapse pit caused by mining is developed and utilizated and the environment ecological system recovered.
