AI Article Synopsis
- The Hp(10) energy response of the Seibersdorf personal dosimeter, which uses two types of filtered LiF:Mg,Ti thermoluminescence detectors, is analyzed using a detailed simulation model created with the MCNP Monte Carlo software.
- The study compares the measured responses from experimental data with those predicted computationally, utilizing a semi-empirical thermoluminescence efficiency function, to evaluate the accuracy of both methods.
- Results show good agreement between the simulated and measured energy responses across a range of photon energies, although discrepancies were noted for the filtered TL detectors at lower energy levels.
Article Abstract
The Hp(10) energy response of the personal dosemeter Seibersdorf and its two different filtered LiF:Mg,Ti (TLD-100) thermoluminescence (TL) detectors are investigated. A close-to-reality simulation model of the personal dosemeter badge including the wrapped detector card was implemented with the MCNP Monte Carlo N-particle transport code. The comparison of measured and computationally calculated response using a semi-empirical TL efficiency function is carried out to provide information about the quality of the results of both methods, experiment and simulation. Similar to the experimental calibration conditions, the irradiation of dosemeters centred on the front surface of the International Organization for Standardization (ISO) water slab phantom is simulated using ISO-4037 reference photon radiation qualities with mean energies between 24 keV and 1.25 MeV and corresponding ISO conversion coefficients. The comparison of the simulated and measured relative Hp(10) energy responses resulted in good agreement within some percent except for the filtered TL element at lower photon energies.
