Dosimetry at high-energy accelerators

چکیده
R É S U M É Les problèmes de la dosimetric dans les champs de rayonnements ionisants diffusés autour des accélérateurs de haute énergie sont présentés. Après une courte introduction sur l'historique des grandeurs physiques utilisées pour l'acquisition de l'équivalent de dose, les techniques diverses pour la dosimétrie dans des champs mixtes à haute énergie sont décrites, en commençant par des mesures spectrales compliquées, puis par la présentation des moyens en multidétecteurs et en instruments sur la base des détecteurs proportionnels. Enfin l'utilisation de méthodes simples est mise en évidence pour le cas où l'on dispose d'une connaissance initiale et supplémentaire sur la composition des rayonnements ionisants. Il est montré que les résultats des mesures correspondent bien à ceux obtenus à l'aide des programmes de calcul modernes.

Since the beginning of the past century, accelerators have started to play a fundamental role as powerful tools to discover the world around us, how the universe has evolved since the big bang and to develop fundamental instruments for everyday life. Although more than 15 000 accelerators are operating around the world only a very few of them are dedicated to fundamental research. An overview o...
متن کاملShielding high energy accelerators.
After introducing the subject or shielding high energy accelerators, point source, line-of-sight models, and in particular the Moyer Model, are discussed. Their use in the shielding of proton and electron accelerators is demonstrated and their limitations noted, especially in relation to shielding in the forward direction provided by large, flat walls. The limitations of reducing problems to th...
متن کاملNeutron dose per fluence and weighting factors for use at high energy accelerators.
In June 2007, the United States Department of Energy incorporated revised values of neutron weighting factors into its occupational radiation protection regulation Title 10, Code of Federal Regulations Part 835, as part of updating its radiation dosimetry system. This has led to a reassessment of neutron radiation fields at high energy accelerators such as those at the Fermi National Accelerato...
