Advancement of airborne radiation measurement technology: (2) Simulations of unmanned helicopter and LaBr3(Ce) detector used for estimating radiocesium distribution in soil


Here we report PHITS Monte Carlo simulations of a LaBr3(Ce) gamma spectroscopy system used in unmanned helicopter radiation surveys in Fukushima Prefecture. The simulated spectra were verified against measurements taken under controlled laboratory conditions. Simulations were used to characterize the peak-to-Compton method for estimating the vertical distribution of radiocesium in soil from airborne surveys.
