“…Some systems are used to monitor the radiation shielding efficiency [47, 48] or to measure the fast neutrons besides gamma rays [49, 50, 51, 52, 53, 54, 55, 56]. In such systems, the use of nanomaterials against radiation would be preferable.…”

Nanoparticles (NPs) indicating a unique potential in bioradiation and nuclear reactor shielding are employed in many fields due to their particular specifications leading improving the mechanical properties as well as pore structure of the concrete-shield. The aim was to introduce a novel coefficient ( ), namely the experimental to theoretical density ratio for mixed-NPs material at various nanoparticles percent concentrations ( ) based on pure mathematical aspects along with the some suitable physical purposes by Monte Carlo method. The change in the mixture density to the change in is always proportional to the value. The density will become maximum at the in which the physical, morphological and chemical features of NPs along with the amounts of voids in the material have a key role over estimating porosity percentage. The NPs’ separation probability as born-cascaded-pairs towards very small radii may be formulated as where and are constant values. In conclusion, the theoretical results may be experimentally used in future work for different applications such as designing shield at a nuclear facility.

A description of the proton (IS SC-1000, IS OP-1000) and neutron (IS NP/GNEIS) test facilities at the 1 GeV synchrocyclotron SC-1000 of the PNPI used for radiation resistance testing of electronic components and systems intended for avionic and space research is presented. A unique conjunction of proton beams with variable energy 100-1000 MeV and atmospheric like neutron beam with broad energy range (1-1000 MeV) spectrum enables to perform complex testing of the semiconductor electronic devices within a single testing cycle.

“…The high-energy neutrons are few for the VESUVIO because the neutrons are moderated by water. The neutron facility at the Petersburg Nuclear Physics Institute (PNPI) has also developed the neutron beam with the atmospheric-like neutron spectrum [20]- [21]. The characteristic of PNPI neutron spectrum shape is harder and close to 1 GeV at the maximal energy comparing with above neutron sources.…”

China Spallation Neutron Source (CSNS) will start commissioning in early 2018. The neutron spectra from the tungsten target bombarding by 1.6 GeV proton beam are very wide, namely white neutron spectra. Two white neutron beams schemed by CSNS are simulated by FLUKA. And the beam spectrum and intensity comparisons with other neutron sources in service are made. The fidelity of neutron spectra of these two whiteneutron beam lines for chip irradiation experiments are estimated. The CSNS atmosphericlike neutron beams will be the first white neutron beam lines in China and the most intensive ones in a few years suitable to carry out the accelerated test experiments of neutron single event effect in the world.
