  1. Individual dosimetry for high energy radiation fields.

    Article, Communication - En anglais

    International Conference on Solid State Dosimetry. Part 2. Burgos, ESP, 1998/07/05.

    The exposure of individuals on board aircraft increased interest in individual dosimetry in high energy radiation fields.

    These fields, both in the case of cosmic rays as primary radiation and at high energy particle accelerators are complex, with a large diversity of particle types, their energies, and linear energy transfer (LET).

    Several already existing individual dosemeters have been tested in such fields.

    For the component with high LET (mostly neutrons) etched track detectors were tested with and without fissile radiators, nuclear emulsions, bubble detectors of both types available and an albedo dosemeter.

    Individual dosimetry for the low LET component has been performed with thermoluminescent detectors (TLDs), photographic film dosemeters and two types of electronic individual dosemeters.

    It was found that individual dosimetry for the low LET component was satisfactory with the dosemeters tested.

    As far as the high LET component is concerned, there are problems with both the sensitivity and the energy response.
