Abstract :
A study on calculation and evaluation on atmosphere radioactive pollution of uranium mine well ventilation exhaust gas is presented in this paper. Neutral atmosphere conditions were taken into consideration. Nuclear industry standards on safety protection distance were analyzed and compared with calculation results. The calculation results show that 500 m distance of radiation safety protection is appropriate, and which is lower than 1000 m distance listed on previous standards. In addition, personal dose at 500m can also meet the requirements of public personal dose limit. According to calculation results, specific pollution control methods on uranium mining and metallurgy area were put forward to reduce the harm and pollution to environment and residents.
