Fast Neutron Dosimetry by Thermoluminescence Detection of Knock-on Protons
A thermoluminescence equivalent to the etched track technique for fast neutron dosimetry is described. It is based on 'reading' thin thermoluminescent (TL) layers with a tightly focused, scanning CO2 laser beam. With a spatial resolution of 30 µm, it detects and counts areas of high TL emission that result from individual knock-on-protons generated in a polyethylene foil.
