Cross sections of He-particle induced reactions on W.

Irradiation of W targets by He particles was carried out. For the first time the cross sections for the reactions of production of Re, Os, W were measured by the stack foil technique in the He energy range of 15-45 MeV. The results were compared to the data from the TENDL-2019 library.

Cross section measurements of Eu(He,5n) reaction: new opportunities for medical alpha emitter Tb production.

Method for production of alpha emitter Tb by irradiation of Eu with 70 MeV He nuclei is proposed. For the first time, the cross sections for the formation of isotopes Tb were measured experimentally using a stack foil technique in the He particles energy range 70 → 12 MeV. The thick target yield of Tb is 39 MBq/μAh, or 230 MBq/μA Tb at saturation.

Mo recoil atoms yield in the Mo(p,x) reaction on cyclotron irradiation of Mo nanofilms.

We study the possibility of increasing the specific activity of Mo produced by irradiating molybdenum targets with the use of the Szilard-Chalmers effect. According to the Szilard-Chalmers effect, recoil atoms of the Mo radionuclide can be produced in nuclear reactions and retained in surrounding buffer substance. The objective of our work is to measure the yield of recoil atoms in the buffer as a function of the molybdenum layer thickness.

Suppressed neurogenesis without cognitive deficits: effects of fast neutron irradiation in mice.

This study assessed the effects of combined low-dose neutron and γ-ray irradiation on hippocampal neurogenesis and hippocampal-dependent memory. Neural progenitor cell division and survival were evaluated in brain sections and whole hippocampal preparations following head irradiation at a dose of 0.34 Gy for neutron radiation and 0.
