Radioisotopes produced by neutron irradiation of food [PDF]
Applied Radiation and Isotopes, 2016 The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only

Defects in neutron irradiated molybdenum [PDF]
Acta Metallurgica, 1967 Abstract Molybdenum of purity 99.965% has been examined by transmission electron microscopy and field ion microscopy before and after neutron irradiation to 1 × 1019 n.v.t. at reactor ambient temperature. The structure after 1 hr anneal at 760°C following irradiation was also investigated.

Effects of Fast Neutron Irradiation on Switching of Silicon Bipolar Junction Transistor [PDF]
Journal of Radiation Protection and Research, 2023 Background When bipolar junction transistors (BJTs) are used as switches, their switching characteristics can be deteriorated because the recombination time of the minority carriers is long during turn-off transient.
