Eext = Dext × Te × Fd × A (1) Einh = Dinh × Te × Fd × Br × Cdust × A (2) Eing = Ding × Te × Fd × Ring × A (3) where Eext, Einh, and Eing are the effective doses due to external gannma radiation, inhalation, and ingestion exposures (Sv y-1). Dext, Dinh, and Ding are the dose coefficients for external gannma radiation, inhalation, and ingestion exposures.(Sv h-1 per Bq g-1 for Dext) (Sv Bq-1 for Dinh, and Ding) Te is the exposure time (y-1) Fd is the dilution factor A is the activity in samples (Bq g-1) Br is the breathing rate (m3 h-1) Cdust is the dust concentration during exposure time (g m-3), and Ring is the ingestion rate (g h-1) Natural resources such as ore are mainly included U-238 series, Th-232 series and K-40. Therefore, following equations were used to estimate a total effective dose for workers. Eext (total) = Eext (U)+ Eext (Th)+ Eext (K) (4) Einh (total) = Einh (U)+ Einh (Th)+ Einh (K) (5) Eing (total) = Eing (U)+ Eing (Th)+ Eing (K) (6) Etotal = Eext (total)+ Einh (total)+ Eing (total) (7) where Eext (U), Eext (Th), and Eext (K) are the Eext for U-238 series, Th-232 series, and K-40, respectively. (Sv y-1) Einh (U), Einh (Th), and Einh (K) are the Einh for U-238 series, Th-232 series, and K-40, respectively. (Sv y-1) Eing (U), Eing (Th), and Eing (K) are the Eing for U-238 series, Th-232 series, and K-40, respectively. (Sv y-1), and Etotal is the total effective doses of amount of external gannma radiation, inhalation, and ingestion exposures due to U-238 series, Th-232 series, and K-40. (Sv y-1)
