Participation of the Laboratoire d'Exploitation Dosimetrique du Centre d'Etudes Nucleaires de Fontenay aux Roses in the IAEA intercomparison program

The Centre of Nuclear Studies at Fontenay aux Roses used both TLD and film dosimeters for the Intercomparison. Two 7LiF pellets were used in the dosimeter. One is under an open window (covered only by the 30 mg cm-2 PVC envelope), and the other covered with 330 mg cm-2 plastic material, including the envelope. Six different filters are used in the film dosimeter. Calibration is performed free in air using 60Co. Simple algorithms are used to determine air kerma and the dose equivalent quantities with the TL dosimeter. The film dosimeters are evaluated in two ways to determine dose. These techniques are described. (orig.)
