Active personal dosemeters for individual monitoring and other new developments

Abstract

In this paper, we will present a first (but not complete) status description of active personal dosemeters (APDs) and their implementation in European countries. In modern radiation protection practices, APDs are becoming absolutely necessary operational tools for satisfying the ALARA principle. Despite their success, they are relatively new for individual monitoring of workers. Regulation, legal requirements and calibration procedures are different in European member states. A catalogue of commercially available and prototype devices is presented. Improvement on devices and in implementation of calibration method are expected in the forthcoming years. End-user feedback experience and requirements are reported.

Assessment of Patient and Occupational Dose in Established and New Applications of MDCT Fluoroscopy

“…These electronic personal dosimeters were attached outside the lead apron on the breast pocket. The semi conductor-based dosimeter provides a direct read of the occupa tional dose equivalent, H p (10), at a resolution of 1 µSv and is sufficiently sensitive for measurement of relatively low photon energies [5]. The elec tronic personal dosimeter was used in addition to the required thermoluminescent personal dosimeter [6].…”

Methodology for Simultaneous Relative-calibration of Multiple Personal Dosimeters in a ²²⁶Ra Irradiation Field

“…In addition, by redesigning the geometric con guration of the support units, the eld could be used for other types of gamma-ray dosimeters. 4,7,8) An irradiation eld for neutron dosimeters will be reported elsewhere.…”

2-D Gem-Based Tepc for Neutron Protection Dosimetry

“…Many designs of active neutron dosimeters have been proposed and some are available commercially. A thorough review of active personal dosimeters was performed by Bolognese-Milsztajn et al [6] who found that most commercially available units suffer from a severe energy dependence that can lead to the underestimation the dose equivalent of up to a factor of 100 at some energies [6]. These devices usually have, as the sensing element, a Silicon pin diode surrounded by 10 Bi or 6 Li rich secondary charged particle "producer".…”
