[en] The device comprises a longitudinally pliable strip to which a dosimeter is fixed at approximately mid length. Both strip and dosimeter are surrounded by a tube of shrinkable rubby material which almost partially shrinks to close fit the strip on either side of the dosimeter. This results in a recording device easily manufactured as a throw away article which is insensible to external influences, can be readily worn at a variety of body locations, can be indelibly marked and is hygienic

[en] Since the implementation of the ICRU (International Commission on Radiation Units and Measurements) in national law by the Radiation Protection Ordinance (StrlSchV 2001) and the X-ray Ordinance (RoeV 2003), new measuring units have become valid for personnel dose metering. From the end of the transition period (August 2006), only electronic dosemeters have been in use, and producers of other types of dosemeters have stopped production. Electronic dosemeters with direct reading are presented that meet the legal specifications. (orig.)

[en] The direct ion storage (DIS) dosemeter is based on the combination of an ion chamber and a non-volatile electronic charge storage element. This allows a new type of passive dosemeter to be constructed with dosimetric characteristics ideally suited for measuring the H_p (10 and H_p 0.07) operational quantities. The DIS dosemeter is a passive device by nature but a direct non-destructive readout capability allows it to be used also as the detecting element in a personal alarming dosemeter. The features and benefits of an electronic legal dosemeter (ELD) system are described and the operational characteristics and specifications are presented and compared with conventional solid state and electronic dosimetry systems.

[en] The Cea has the obligation to declare any discrepancy occurred in its installations or during a nuclear transport. In 2009, 122 events were declared to the French nuclear safety authority. None of them had sanitary consequences on the staff, the public or the environment. However, 1 event was graded 2 on the Ines scale: the amounts of plutonium recovered from the dismantlement of glove boxes were greater than the quantity accounted during their operational life. This event has triggered a general inspection of any similar places of retention in Cea installations. As for radiation protection of the employees (from the Cea and from enterprises working on Cea facilities) the doses are below 1 mSv. The Cea is working on a safety approach concerning the handling of nano-materials. (A.C.)

[en] Results of the second national intercomparison of personal dosemeters are presented. We have chosen only the results for 70 kV X radiation quality which are relevant for radiological diagnostics. All results show dispersions which are probably caused by using various dosemeter types of various producers as well as by using non-uniform calibration conditions. (author)

[en] Three general reasons for undertaking statistical studies of occupational exposure to radiation are identified. Some important points to be considered in such analyses are given and some interesting questions for future research are identified. (author)

[en] This publication has the character of a set of recommendations towards in practice working radiation protection specialists who are involved within their company or institute with the organization and performance of measurements in order to control the individual radiation burden caused by external exposition and internal contamination in applying radioactive materials and radiation apparatus. This publication gives information about the practical performance of personnel dosimetry at external exposure with a personnel dosimeter, which is carried on the body. The individual control of internal contamination is a much more complicated task. This publication assumes, with regard to this part, that people who are involved with it have been schooled as a radiation specialist level-3. For this part this publication contains numerical information needed for assessing of the individual effective follow-dose equivalence in occurring cases. A list with data of much used radionuclides is included. Also dosimetric data are presented which may be useful in case of contamination of skin and wounds. (author). 14 refs.; 2 figs.; 17 tabs

[en] This product review describes recently developed equipment for personnel dosimetry, area monitoring, personnel contamination monitoring, portable contamination monitoring and portable area survey monitoring. (author)

[en] Many theoretical concepts concerning radiation protection quantities have been discussed during the past 20 years. Considering radiation protection dosimetry from a practical point of view, it is already a powerful tool which contributes to minimising exposure by prompting protective action when incorrect situations are discovered. The conclusion is that the most important aim in radiation protection should not be a very sophisticated dosimetry, but a reduction of exposures down to levels where simple survey becomes sufficient.

[en] The calibration of a personal dosemeter/dosimetry system is the determination of the relationship of the magnitude of the response of the dosemeter/dosimetry system to the magnitude of a given quantity. The term calibration includes type testing where this relationship is determined throughout the range of applicable radiation fields, and also routine performance assessment where only a few field conditions may be used. The method of calibration and whether and what form of phantom is required depends on the quantity to be estimated. Where this quantity is one defined in the human body or in a phantom, calibration will normally be carried out on a phantom. This paper discusses the choice of quantity and choice of phantom. (author)
