METHODICAL APPROACH TO THE RECONSTRUCTION (VERIFICATION) OF DOSES RECORDED BY INDIVIDUAL FILM DOSIMETERS
In the framework of the Mayak PA Worker Exposure Dose Study sponsored by the US DOE methods for verification of readings of film dosimeter that were used at the Mayak PA for personnel exposure doses monitoring from 1948 to 1992 were proposed. These methods are based on calculation of a ratio of absorbed doses in film dosimeters emulsion and in air for calibration conditions and for real geometry of personnel exposure using Monte-Carlo simulations and MCNP code. To verify the methods experimental studies were performed at the GSF Secondary Standards Laboratory (Munich, Germany). The methods served as a basis for individual dose reconstruction under conditions of dosimeters use in real spectra and photon radiation geometries at the "Mayak" PA production areas.
