Stadistical criteria to estimate the internal doses in workers exposed to radioactive airbornes

Abstract

The regulations require that monitoring of intake of radioactive material should be applied depending on radiological hazards but they do not establish precise criteria how these radiological hazards should be evaluated. Using the data from Juzbado Uranium Plant, we have made an statistical study of air sampling concentration and of the intake of a group of workers exposed to inhalation of uranium aerosols. We have found that these can be fitted to the probability distributions. Applying these distributions we have used simulation techniques to evaluate the hazards from intake. All these methods can be useful for the design and the conduct of the air control monitoring and to classify the risk for a specific workshop.
