摘要：

The activity concentrations of U-238, Ra-226, Th-232, and K-40 in 56 phosphate samples (phosphate rocks, monocalcium, and dicalcium phosphates) used in Serbia were determined using gamma spectrometry to assess the exposure level of workers. Radium equivalent index (Ra-eq), absorbed gamma dose rate (D-R), annual effective dose (AED), and excess lifetime cancer risk (ELCR) were evaluated. The highest external exposure was recorded when working with phosphate rocks, as Ra-eq, D-R,D- and ELCR exceed the recommended/average values. The annual effective doses for workers in the phosphate industry are below 1 mSv y(-1) and comparable to the values from other studies.
