[en] This guide presents more than two hundred cards treating the most encountered radionuclides. These data will help the user in order to help him to quantify the risk of internal or external exposure linked to handling; in order to optimize the detection, the means of protection as well the equipment and working stations. This new edition is established from the last international recommends and use recent French and European legislations. This work is part of the special numbers of the radiation protection journal. (N.C.)

[en] This practical guidebook concerns all scientific and technical sectors where radioactive compounds are used or handled: medicine, biology, nuclear research and industry, radioprotection activities. It presents more than 200 files dealing with the most common radionuclides used in these sectors. Each file presents the nuclear characteristics, the risks of internal and external exposure linked with the handling of these radionuclides, the optimization of their detection, the protection means and the working equipments. This last edition has been fully updated using the most recent international recommendations and the new French and European legislation. (J.S.)

[en] This handbook is a reference source of radionuclide and radiation protection information. Its purpose is to provide users of radionuclides in medicine, research and industry with consolidated and appropriate information and data to handle and transport radioactive substances safely. It is mainly intended for users in low and intermediate activity laboratories. Individual data sheets are provided for a wide range of commonly used radionuclides (144 in total). These radionuclides are classified into five different groups as a function of risk level, represented by colours red, orange, yellow, green and blue, in descending order of risk (author)

[en] This handbook provides the most up to date internal and external dosimetry information and control criteria in the form of data sheets in an easy to use format for 108 of the most commonly used radionuclides in medicine, research and industry. It is designed as a ready reference source of information, gathering together in one place, in the form of individual datasheets, the most up to date isotopic and radiation protection data. (author)

[en] Radiological characterisation of an experimental chamber and other areas of an ultra-high intensity laser facility (∼terawatt) revealed significant levels of X ray, gamma and neutron radiation. Different techniques were used to detect and measure this radiation: TLD, photographic film, bubble detectors and germanium spectrometry. A test series of radiological measurements was made for 150 laser shots (300 femtoseconds) with energies in the 1 to 20 J range and a target illuminance of 10¹⁹ W.cm^-2. Gamma dose equivalents in the vicinity of the chamber varied between 0.7 and 73 mSv. The dose equivalent due to the neutron component was evaluated to be 1% of the gamma dose equivalent. The amount of radiation generated depends on the laser energy and the nature of the target. No activation or contamination of the chamber or target holder were observed. Ultra-high intensity lasers are being extensively developed at the present time and the investigations performed demonstrate that it is necessary to take radiological risks into consideration in the design of ultra-high intensity laser facilities and to define personnel access conditions.

[en] Non invasive methods of study of the skin blood flow are numerous, but generally do not give any indication on the cutaneous micro-circulatory flow, except for cutaneous laser Doppler. The isotopic exploration of the skin with injected γ radionuclides, even of weak energy, doe snot allow to characterize the skin blood flow, because of the important contribution of the subcutaneous tissues. The use of β emitters energy spectrum, analyzed by different quantitative methods, are proportional to the thickness of the screen localized between the radioactive source and detector. Using simple and complex phantoms composed of tissue equivalent screens, with ³²P sources placed at different depths, it was possible to study the degradation of β spectra, simulating respectively the sub-epidermis and sub-dermis vascular levels. A modelization and an experimental study in-vivo are proposed in this work, with ³²P phosphate administered intravenously in pigs. (author)

[en] A study of dosimetric errors is under way within an international collaborative study of cancer risk among workers in the nuclear industry. The objective is to quantify errors in the estimated photon doses to individual organs used for cancer risk estimation. One source of errors is the response of old dosemeters in workplace exposure conditions. As these conditions are not well known, the International Study must rely on expert estimates. This paper describes a method to assess the proportion of the dose from photons in three energy ranges (<100, 100-300, (300 keV) using the responses under filters of a multi-element dosemeter. The method was tested on experimental and simulated data and provides a good estimate of the proportion of dose from photons below 100 keV, the most critical for dosemeter response. It was applied to personnel readings in one facility, confirming the experts' estimation. Beyond the International Study, the method has implication for the monitoring and protection of workers.

[en] This practical guidebook is an upgrade of the previous edition of 2006. It concerns all scientific and technical sectors where radioactive compounds are used or handled: medicine, biology, nuclear research and industry, and radiation protection activities. A preliminary section recalls the main notions of radiation physics and radiation protection. Then, a corpus of 212 files with the most commonly used radionuclides is introduced. Each file aims at quantifying the internal and external exposure risks linked with the handling of these radionuclides, and at optimizing the detection and protection means, and the equipments and workplaces. This last edition has been fully updated with respect to the most recent international recommendations and the new French and European legislations
