“…The comparison exercise was finished by 15 of the 16 participants which solved task one (Vrba et al, 2014b). Five of the participants (one third) needed revision or help with their simulations.…”

“…This means that only the radioactive bone in half of the BPAM-001 phantom was used for the source of the primary particles (photons). Yields and energy of the photons emitted during decay of 241 Am were stated in the main inter-comparison document and is same as for task one (Vrba et al, 2014b).…”

“…This task was for participants who had already calibrated their PBC system previously with another physical skull phantom or who are using Monte Carlo methods to calibrate their systems. Several of the participants also participated in the EURADOS Monte Carlo skull phantom intercomparison (Vrba et al, 2015;Vrba et al, 2014b). To be consistent, the same participant ID was used here, for those who participated in both intercomparisons.…”

In 2011 a measurement intercomparison was launched by EURADOS WG7, with the objective of providing the participants with the tools to calibrate their detection systems for detection of 241 Am in the skull bone, and evaluate the variability due to the used of the different calibration phantoms. Three skull phantoms were used in this intercomparison: the USTUR Case 0102 skull phantom, the BfS skull phantom and the CSR skull phantom. Very good agreement was found between the results of the twelve participating laboratories, with relative deviations of less than 15% for the BfS phantom and less than 17% for the USTUR phantom when measurement efficiency in defined positions was compared. However, the phantoms' measured absolute 241 Am activities showed discrepancies of up to a factor of 3.4. This is mainly due to the physical differences between the standard calibration phantoms used by the participants and those used in this intercomparison exercise.

“…Though calibration must be performed with physical source (according to the accreditation authorities requirements). Although Monte Carlo calculation is not considered by accreditation authorities, it is often used for the preliminary calibration, for example, for choosing appropriate measurements geometry [1], material for phantoms or for interlaboratory comparison purposes [2,3].…”

Abstract. The aim of this study was to develop a numerical model of spectrometric thyroid counter, which is used for the measurements of internal contamination by in vivo method. The modeled detector is used for a routine internal exposure monitoring procedure in the Radiation Protection Measurements Laboratory of National Centre for Nuclear Research (NCBJ). This procedure may also be used for monitoring of occupationally exposed nuclear medicine personnel. The developed model was prepared using Monte Carlo code FLUKA 2011 ver. 2b.6 Apr-14 and FLAIR ver. 1.2-5 interface. It contains a scintillation NaI(Tl) detector, the collimator and the thyroid water phantom with a reference source of iodine 131 I. The geometry of the model was designed and a gamma energy spectrum of iodine 131 I deposited in the detector was calculated.
