Fast Neutron Dosimetry and Spectrometry Using Radioactivation; DOSIMETRIE ET SPECTROMETRIE DES NEUTRONS RAPIDES PAR RADIOACTIVATION
Technical Report
·
OSTI ID:4697116
A review of general information concerning induced radioactivity detectors is presented along with tables summarizing the properties of detector elements which may be used in radioprotection. The excitation functions found in the literature are also given. The technological characteristics of the detectors used are given, together with the counting methods. The many advantages of activation dosimetry for strong or periodic neutron fluxes and for those in the presence of gamma -radiation are stressed. The main problem in activation dosimetry is, however, the calculation of the dose absorbed from the results of the measurements. It is shown how the dose is expressed, fairly accurately, as a function of the radioactivities induced in a series of detectors. As an example, the spectrometry and the dosimetry of the neutron flux emitted by a Po -Be source are presented. (auth)
