BACKGROUND The recent spread of positron emission tomography-computed tomography (PET/CT) poses extremity dosimetry challenges. The question arose whether the radiation dose measured by the ring thermoluminescent dosimeter usually worn on the proximal phalanx (P1) of the index finger measures doses that are representative of the true doses received by the upper extremities of the operators. A p...

Routine internal dose exposures are typically (in the UK nuclear industry) less than external dose exposures: however, the costs of internal dosimetry monitoring programmes can be significantly greater than those for external dosimetry. For this reason decisions on when to apply routine monitoring programmes, and the nature of these programmes, can be more critical than for external dosimetry p...

This work intend to identify and follow up quality control parameters to improve thermoluminescence dosemeter (TLD) system used for personal dosimetry in ionizing radiation metrology laboratory (IRML). Characterization of personal dosimetry system has presented in terms of the stability of reader calibration factors, linearity of response for Cs as reference radiation source, energy and angular...

For field research of non-visual effects light, accurate measurement personal light exposure is required. A consensus framework for light-dosimetry could improve and ensure comparability between studies. Here, we present a review methodologies used in studies published to date, focussing on considerations regarding the preparation data. Overall, large variability studies’ observed, highlighting...

The basis for personal dosimetry performance testing in the United States is ANSI/HPS N13.11. Now in it's fourth edition, this standard has been in place since 1983. Testing under this standard is administered by the National Voluntary Laboratory Accreditation Program (NVLAP), and accreditation of dosimetry processors under this program is required by U.S. Nuclear Regulatory Commission (NRC) re...

The objective of this paper is to provide an overview the current status in neutron personal dosimetry based on poly allyl diglycol carbonate (PADC), also commonly known by commercial name CR-39, summarize best practices field, and point future research directions. An fundamentals technique given, including a discussion PADC material, main parameters characteristics, practical considerations, a...
