On microdosimetry of neutrons of selectable energy in mixed (n,y) fields [PDF]

open access: yes, 2012
Biological damage of tissue due to intermediate energy neutrons is generally known to be very important in radiobiology and radiation protection. However, there is no suitable method to determine the quality of these neutrons in particular in the working

Fast neutron fluence estimation by measurement of93mNb and93Mo

open access: yesEPJ Web of Conferences, 2023
The possibility for estimation of fast neutron fluence from93mNb produced from Nb contained in structural component materials of nuclear power plants was investigated as an evaluation tool for extending plant operating lifetime. First, to establish a measurement method for93mNb in structural component materials, chemical separations and measurements ...

ELECTRIC CONDUCTIVITY OF ALUMINUM ALLOYS DEPENDING ON FAST NEUTRON FLUENCE

open access: yesPHYSICAL AND MATHEMATICAL SCIENCES, 2020
The nonlinear dependence of the resistivity on the dose and temperature was determined. On the basis of X-ray structure of the alloy is shown that the alloy SAV-1 is a solid solution in which the average static mixing of atoms in order of magnitude compared with their dynamic displacements caused by thermal motion.

Study of Fiber Bragg Grating Samples Exposed to High Fast Neutron Fluences [PDF]

open access: yesIEEE Transactions on Nuclear Science, 2018
Fiber Bragg grating (FBG) sensors are expected to provide valuable data in extreme radiation environments associated with nuclear research reactors. However, when the fast neutron fluence reaches 1018–1019 n/cm2, the radiation-induced changes in the material density and refractive index may drastically bias the measurements.

Neutron fluence and dose measurements by optical fibers

open access: yes, 2022
S.290-295It is shown that fibers doped with (Ge + P) or with (GE + B) can be used with good accuracy for fluence determinations of fast or slow neutrons, respectively, when they are calibrated at sources of known flux.
