3.11.2 Technical Aspects of the Neutron Generator Safety
ere are two main hazards with NGs: the electrical hazard and the radiation
hazard.
3.11.2.1 Electrical Hazard
As seen in previous chapters, NGs generate neutrons thanks to a nuclear
reaction obtained in a target on which ions have been accelerated by an
electrical eld. To obtain a high level electrical eld (typically 100 kV/cm), a
high voltage power supply (typically 100 kV) is needed. However, if the gen-
erator is designed according to the norms of the manufacturer, there a ...
