Solid state detectors for dosimetry in the BNCT beam of the LVR-15 research reactor

Dosimetry measurements have been carried out at the epithermal neutron beam of LVR-15 reactor (Řež) moderated by a polyethylene disk placed through the collimator exit. The spatial distributions of thermal neutron fluence rate and of gamma and fast neutron dose rates have been attained. The contributions to the dose of the radiation field components have been assessed with Fricke-gel-layers, by pixel-to-pixel elaboration of the light transmittance images of samples having different isotopic composition and with thermoluminescence detectors, by analysing the shape of the glow curve. An analogous experiment has been carried out at the thermal column HK1 of the same LVR-15 reactor, aimed at neutronography research. Good consistency of all results was obtained.
