Occupational radiation exposure from mining naturally occurring radioactive materials (NORM) is a challenge. A pilot study found elevated uranium, thorium, and polonium levels in workers at coal, niobium, and monazite sand mines.

Area of Science:

  • Occupational health
  • Radiation protection
  • Environmental science

Background:

  • Mining and processing of uranium and thorium minerals can lead to significant radiation doses for workers.
  • Controlling occupational exposures from naturally occurring radioactive materials (NORM) presents challenges for regulatory bodies and radiation protection experts.

Purpose of the Study:

  • To assess occupational radiation exposure in Brazilian mining and mineral processing facilities.
  • To evaluate the effectiveness of internal dosimetry programs for NORM workers.

Main Methods:

  • A pilot survey program was conducted at six mines and one monazite processing plant in Brazil.
  • Uranium, thorium, and polonium concentrations were measured in urine, feces, and air samples from workers.
  • Worker data were compared with background levels from local families and the general population of Rio de Janeiro.

Main Results:

  • Elevated levels of uranium, thorium, and polonium were detected in workers from coal mines, niobium mines, and the monazite sand plant.
  • The study identified specific worker groups with positive exposure results, indicating potential risks.

Conclusions:

  • The findings highlight the need for robust internal dosimetry programs to manage occupational exposures in NORM industries.
  • Difficulties in applying these programs underscore the challenges in effectively controlling radiation risks for NORM workers.
