Tolerance Flux of Thermal Neutrons [PDF]

Nature, 1949
THE danger of neutrons on the human body arises from two factors : the slowing down of fast neutrons and the absorption of neutrons. In the case of thermal neutrons, only absorption can take place, either in hydrogen to form a deuteron with emission of a 2.2-MeV. γ-ray, or by nitrogen-14 to form a carbon, with the emission of a 0.7-MeV. proton.

Thermal neutron intensity measurement with fission chamber in current, pulse and Campbell modes [PDF]

EPJ Web of Conferences, 2020
In thermal nuclear reactors, most of the power is generated by thermal neutron induced fission. Therefore, fission chambers with targets that respond directly to slow neutrons are of great interest for thermal neutron flux measurements due to relatively ...

Implications of Hyperon Pairing for Cooling of Neutron Stars [PDF]

, 1998
The implications of hyperon pairing for the thermal evolution of neutron stars containing hyperons are investigated. The outcome of cooling simulations are compared for neutron star models composed only of nucleons and leptons, models including hyperons,

Fabrication and Characterization of K₂CeCl₅/⁶LiCl and CeCl₃/SrCl₂/⁶LiCl Eutectics for Thermal Neutron Detection

Crystals, 2022
In recent years, thermal neutron detection using scintillators has been used in a wide range of fields. Thus, the development of scintillators with a higher light yield, faster decay, and higher sensitivity for thermal neutrons is required. In this study,
