Abstract

Existing sensors in active personal neutron dosemeters are invariably based on silicon semiconductors. These are compact and provide a signal that is easy to interface to the processing electronics. However, their response as a function of neutron energy differs considerably to that of body tissue, causing such dosemeters to read incorrectly when used in fields for which they have not been calibrated.
A literature study identified several novel neutron detector technologies that offer the potential for an improved dose response. Those technologies are set out and discussed in this report. It is intended that, in a future project, samples of devices from among these technologies will be obtained and tested experimentally.
