This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.
This is neat work! I would comment that when dosimetry companies use CR-39 detectors for neutron exposure, they also cover a section of CR-39 with boron to measure thermal neutrons via the 10-B(n,a) reaction, so that may be an area of interest to explore as well. Small pieces of boron nitride show up on eBay regularly and it is an easy material to work with.
