Аннотация
Occupational exposures to radiation during chemical treatment of black sand minerals (ilmenite, zircon, monazite, rutile) were evaluated. Additive effective dose rate (AEDR) is a new measure introduced to control the occupational exposure to radiation. The value of AEDR from the external γ-rays was estimated at 1.06 × 10–9 Sv h–1 kBq–1. Based on the dose conversion coefficients obtained by the previous epidemiological studies, AEDR from radon and thoron gases was found to be 2.7 × 10–9 and 1.52 × 10–9 Sv h–1 kBq–1, respectively. The batch effective dose (BED) was suggested as a real alternative to the average effective doses over different locations. It is concluded that 1 kBq of a natural radioactive mineral adds an occupational effective dose of 9.52 × 10–5 Sv year–1.
