Health Risk Assessment of Airborne Radon and its Daughters from Uranium Ore District by Monte Carlo Simulation

Abstract:

The monitoring data of radon concentration in a uranium ore district were taken as the evaluating objects in this paper. Carcinogenic risk was evaluated by health risk assessment four-paragraph method put forward by the national academy of sciences (NAS). Then the quantitative analysis was performed to evaluate the probability of radon and its daughters’ carcinogenic risk. Monte-Carlo technology was carried on to establish the model of simulation, and the Crystal Ball software was used to calculate quickly. The results show that effective dose will be still less than 1 mSV restricted by GB18871-2002 until 94.99% and the mean of carcinogenic risk is 1.40 ×10-7. The further protection measures are necessary near the sources of pollution according to the distribution of radon concentration.
