Dose Equivalent Response of Personal Neutron Dosemeters as a Function of Angle
Radiation Protection Dosimetry, 1997The measured and calculated dose equivalent response as a function of angle has been examined for an albedo-type thermoluminescence dosemeter (TLD) that was exposed to unmoderated and D 2 O-moderated 252 Cf neutron sources while mounted on a 40 x 40 x 15 cm 3 polymethylmethacrylate phantom.

EUROMET.RI(I)-S1: personal dose equivalent comparison between the BEV and the PTB
Metrologia, 2002A personal dose equivalent comparison was carried out between the BEV and the PTB using a direct-reading electronic dosemeter system as a transfer instrument. This was the first comparison for the `new' operational quantity, Hp(10), for individual monitoring of strongly penetrating radiation and was performed in the preparatory stage of ...

Applied Radiation and Isotopes
This study aimed to evaluate the annual occupational radiation exposure of technologists during PET/CT imaging in 2020 and 2021. Eleven nuclear medicine technologists were monitored at the PET/CT department. The personal dose equivalents (PDEs) for staff members, measured in terms of Hp (10) and Hp (0.07), were assessed annually, considering both deep ...

A study was performed on the measurement of the effective dose equivalent (EDE) with a personal thermoluminescent dosimeter. A Rando phantom with dosimeters inserted at the sites of the tissues specified by ICRP Publication 26 (ICRP77) was exposed at selected locations inside nuclear power stations.

Personal dose equivalent angular response factors for photons with energies up to 1 GeV
Radiation Protection Dosimetry, 2012When performing personal dosemeter calibrations, the dosemeters are typically irradiated while mounted on slab-type phantoms and oriented facing the source. Performance testing standards or intercomparison studies may also specify various rotational angles to test the response of the dosemeter and associated algorithm as this rotation introduces ...

Calculation of the Personal Dose Equivalent, Hp(10), for Neutrons in the MIRD Phantom
Radiation Protection Dosimetry, 1997The personal dose equivalent, H p (10), was calculated in the anthropomorphic MIRD phantom. H p (10) is compared with the primarily limited quantities, the effective dose, E, and the effective dose equivalent, H E , computed in the same Monte Carlo run.
