Dose assessment methodology for the uranium mill workers at different geo chemical environment

Estimation of dose to the radiation worker is being carried out using area monitor, data on radiation level, radon thoron & progeny, airborne long-lived activity and TLD record as applicable in different unit. The present work established the uniform dose computation methodology to estimate the collective dose of an individual worker of uranium mill present in different geo-chemical environment. The methodology is effective enough in minimizing discrepancy the estimation of collective exposure of the individuals in different milling sites. The present work helped in harmonising the collective dose estimation at different mining sites
