Neutron Reaction Characteristics in LiF Crystals Irradiation
نویسندگان
چکیده
The mean effective cross sections of 6Li for the (n, u) reaction were calculated for thermal, intermediate and fast neutrons; this reaction is dominant in damage production in LiF crystals. The actual neutron spectrum was determined from measurements of thermal, intermediate and fast neutron fluxes, in the core of the IEA-RI-2MW swimming pool reactor, in high fluence conditions, by the activation analysis of special detectors. Percent contributions for the 6Li(n, a) 3H reaction were calculated taking into account neutrons in different energy intervals as well as percent contributions of different neutron interactions with LiF.

Using LiF crystals for high-performance neutron imaging with micron-scale resolution
This paper describes an overview of our recent discovery – clear demonstration that LiF crystals can be efficiently used as a high-performance neutron imaging detector based on optically stimulated luminescence of color centers generated by neutron irradiation. It is shown that the neutron images we have obtained are almost free from granular noise, have a spatial resolution of ∼5.4 μm and a li...

Boron neutron capture therapy (BNCT) is an effective method for treatment of deep seated brain tumors. This method consists of two stages: injection of boron compound in the patient body, and then irradiation of the region tumors with the neutron beam. It allows for delivery of high linear energy transfer (LET) radiation (particles 4He and 7Li nuclei) to tumors at the cellular level whilst avoi...

Due to importance of combination therapies in cancer treatment, this study was performed to find the effects of hyperthermia and neutron irradiation and heir combination on the human lymphocytes. Blood samples were treated separately with 41.5 °C for 30 and 60 minutes, 43 °C for 15 and 30 minutes, as well as 10 cGy neutron irradiation. They also treated with hyperthermia followed by irradiation...

One of the most important results of neutron irradiation on targets is that atoms are displaced from their lattice sites after that a nuclear reaction. The neutron irradiation damage is often simulated by using light/heavy ion irradiations, which prepare flexible irradiation conditions. The knowledge of primary knock-on atoms (PKA) and point defect energy distribution is the first step to simul...
