Calibration of an albedo dosemeter at CV-28 cyclotron; Calibracao de um dosimetro de albedo no ciclotron CV-28

Abstract

This work deals with the analysis and application of neutron measurement techniques in order to obtain information on the neutron spectrum and neutron dose equivalent at several representative working places of the cyclotron laboratory of the Instituto de Engenharia Nuclear at Rio de Janeiro, Brazil. Bonner spheres and foil activation were used for the neutron spectra measurements and the neutron dose equivalents were measured with the single sphere albedo technique from the Kernforschungszentrum Karlsruhe, B F{sub 3} and {sup 3} He proportional detectors and {sup 6} Li I scintillation detector. The brazilian albedo dosemeter was calibrated with the single sphere albedo technique. Calibration factors were found for routine applications, when the workers are protected by the shieldings and for radiological accident application, in case a worker is exposed inside the irradiation rooms.
