Arterial wall damage by x-rays and fast neutrons

Trabecular bone changes induced by fast neutrons versus gamma rays in mice

Background: The trabecular bone changes in the tibia of C3H/HeN mice were measured 12 weeks after whole body irradiation with various doses of fast neutrons (0-2.4 Gy) or 137Cs-generated gamma-rays (0-6 Gy). Materials and Methods: Serum calcium, phosphorus, estradiol concentration and alkaline phosphatase activity were measured. Tibiae were anal...

Bimodal Imaging Using Neutrons and X-rays

Experiments that combines the information from two different radiation sources can provide more information than experiments using single radiation sources. This claim was confirmed using the bimodal installation at the thermal neutron imaging beamline NEUTRA at Paul Scherrer Institut. This installation is equipped with a 60-320kV X-ray source and is used for mid-sized samples. The combination ...

Digital pulse-shape discrimination of fast neutrons and γ rays

Discrimination of the detection of fast neutrons and γ rays in a liquid scintillator detector has been investigated using digital pulse-processing techniques. An experimental setup with a 252Cf source, a BC-501 liquid scintillator detector, and a BaF2 detector was used to collect waveforms with a 100 Ms/s, 14 bit sampling ADC. Three identical ADC’s were combined to increase the sampling frequen...
