  1. Estimates of the occupational radiological hazard in the phosphate fertilisers industry in Poland.

    Article - En anglais

    The radiological hazard for workers in the phosphate fertilisers industry was assessed based on measurements in five phosphate plants in Poland.

    Measurement of absorbed dose rates in air, gamma doses, radon gas concentrations in air, and concentrations of natural radionuclides (238U, 226Ra, 210Po, 232Th, and 40K) in samples of raw phosphate rocks, products and byproducts were performed using an ionisation chamber, thermoluminescent detectors, solid state nuclear track detectors, alpha and gamma spectrometry, respectively.

    Using models for dose estimates, individual occupational doses were evaluated for phosphate industry workers involved in the production of fertilisers.

    On average, the estimated dose for yearly exposure ranged from 2.8 to 5.6 mSv, with the higgest contribution typically coming from phosphate dust.

    This is a significant amount when compared with the value of the annual dose limit of 1 mSv for the public, but still well below the occupational dose limit of 50 mSv per year.
