Abstract
A fast neutron personal dosemeter based on the two-step electrochemcially etched CR-39 detectors has been developed by the “Centre de Radioprotection et de Sûreté” (CRS), in as simple a form as possible to be used in routine monitoring of neutron irradiated workers in Algeria. This paper presents the dosimetric characteristics of the developed dosemeter such as energy and angle dependence, dose equivalent response and low limit of detection which are much improved compared to our previous work. The obtained energy response is both flatter (±25%) and extended to lower energy (≈25 keV). Also, a lower detection limit of about 90 μSv has been achieved. In addition, the evaluation of the energy response in term of track size distributions has been performed.
