Based on the high-flow xenon-source scientific device HINEG, the ultra-sensitive dose range of high-energy neutrons to nematodes was found.

Recently, the research team of the Institute of Nuclear Safety Technology of hefei Institute of Material Sciences of the Chinese Academy of Sciences, based on HINEG, a scientific device for the source of the strong-flow radon, and the Institute of Technical Biology and Agricultural Engineering of Hefei Research Institute, conducted an experiment on the effectofs of high-energy neutron radiation damage, which found the ultra-sensitive dose range of high-energy neutrons against nematodes, and the results were published in the medical journal Journal of The International Of Molecular Medicine.
nematodes have 60% to 80% of human homologous genes, using nematodes to carry out neutron radiation damage effect experiments is of great significance to neutron radiation protection research.
due to the lack of monochromatic high-energy high-flow strong neutron source, so far the international study of radiation damage of high-energy neutrons is still rare.
this experiment is based on the strong-flow xenon neutron source scientific device HINEG, led by the nuclear safety research team, which can produce DC-stabilized single-energy or mixed-spectrum neutrons, with neutron flow strength of 6.4 x 1012 n/s, at the first level of the same kind of device in the international transport.
experiments found that, at the individual level, high-energy neutron radiation on the life of organisms, descendants show edifice positive, in a specific low-dose range (-2 Gy) high-energy neutrons also show edimen;
this study not only provides a scientific basis for high-energy neutron low-dose radiation protection, but also provides guidance for clinical dose setting of tumor radiation therapy and the development of new anti-radiation drugs.
research team said that, as an important experimental platform for research and development of advanced nuclear energy systems and cross-application of nuclear technology, HINEG is open to researchers at home and abroad.
