Article: Low-dose monitoring for occupational exposure and the influence of measurement accuracy Journal: International Journal of Low Radiation (IJLR) 2009 Vol.6 No.1 pp.37 - 42 Abstract: This paper presents the evolution of individual radiation doses received by occupationally exposed workers. The individual doses accumulated over the period 2000-2007 correlated to nuclear laboratory and radiation source (gamma, X-rays) types are in the low radiation range. Dose equivalent Hp(10) was measured by a film dosimeter system; the influence of the measurement accuracy on the results was taken into account. Data were obtained on 170 nuclear facilities in which more than 1000 persons were involved. The statistical data show that persons have been recorded with doses up to 70 mSv during the eight years of study. In these cases the recorded doses do not reach values over the dose limit allowed by the nuclear laws in force, even if the dose assessment is given with an error of about −20% to +45% above the total dose range (0.1 mSv-1 Sv).
