The effects of neutron scattering by matrix hydrogen in geological samples were examined in order to accurately determine their chemical compositions by neutron-induced prompt gamma-ray analysis (PGA). Three different matrix materials including basaltic reference rock sample (JB-2) mixed with chemical reagents including H-containing ones were analyzed by using thermal and/or cold neutron-guide...

The influence of neutron irradiation on the thermal conductivity K of diamond films fabricated by hot filament (HF) and microwave plasma assisted (MPA) deposition has been studied.. The additional thermal resistivity induced by irradiation is similar to that found in single crystal diamond and is due mainly to the formation of clusters of disordered carbon material. Despite a significant differ...

In recent years there has been growing interest in the use of neutron scanning techniques for security. Neutron techniques with a range of energy spectra including thermal, white and fast neutrons have been shown to work in different scenarios. As international interest in neutron scanning increases the risk of activating cargo, especially foodstuffs must be considered. There has been a limited...

One of the radiotherapy has boron neutron capture therapy (BNCT). They may make it easier to kill tumor cells with BNCT. In BNCT, it is important for boron agents, which have high selectively and high accumulation, to be introduced into tumor cells. To date, the main boron compounds used by the clinical study are sodium mercaptododecaborate (BSH) and pboronophenylalanine (BPA). But, there are n...
