US Progress on the Development of Neutron Dosemeters Based on CR-39
Historically at US nuclear facilities, two types of personnel neutron dosemeters have been in routine use: nuclear track emulsion Type A (NTA) film and thermoluminescence dosemeters (TLD) albedo. Both of these dosemeters have energy dependent responses. The neutron energy spectra must therefore be known to interpret the dosemeter results properly. As a result, a new state-of-the-art dosimetry system has been developed within the US Department of Energy (US DOE); Personnel Neutron Dosemeter Evaluation and Upgrade Programme. This system is the combination thermoluminescence dosemeter/etched track dosemeter (TLD/TED). This paper presents US DOE research presently being conducted to enhance further the TED portion of the combination TLD/TED system. The research areas involved include: dose sensitivity, neutron energy range, specialised radiators, self-developing dosemeters, and neutron spectrometry.
