Plant seed neutron irradiation dose distribution device based on compact D-D neutron generator

Abstract

The invention discloses a plant seed neutron irradiation dose distribution device based on a compact D-D neutron generator. The device comprises a side reflector and a plurality of seed placement laminates, the side reflector is a frame structure with an opening at one end, the seed placement laminates are clamped in the side reflector, the seed placement laminates are arranged in the side reflector, and a neutron irradiation area is formed by an area between two adjacent seed placement laminates and the side reflectors. The neutron irradiation area can contain a large number of seeds at a time, the seed placement laminates are evenly distributed up and down in the vertical direction, the neutron absorption dose of the placed seeds appears in a uniform gradient, and after each position where the seeds are placed is numbered, the dose of neutrons absorbed by each seed can be obtained through the Monte Carlo simulation technology, the application range of the compact D-D neutron generator in neutron radiation biological research and irradiation mutation breeding is expanded, and meanwhile a basis can be provided for the neutron radiation biological research and the irradiation mutation breeding.

Description

technical field [0001] The invention relates to the application field of nuclear technology, in particular to a plant seed neutron radiation dose distribution device based on a compact D-D neutron generator. Background technique [0002] Irradiating seeds, roots, stems and other organs of plants with radioactive beams will cause them to produce radiation biological effects and induce mutations. The breeding method of obtaining new varieties through artificial selection and cultivation of radiation-induced mutants is called radiation-induced mutation breeding. Compared with traditional hybrid breeding and natural variation breeding, radiation-induced mutation breeding has a greater possibility of variation, Wide range of variation and many other advantages. After more than 80 years of research, scientists have irradiated different plants with various rays, made a lot of achievements in radiation biological effects and mutation breeding, and accumulated rich research data and...

Problems solved by technology

However, due to the lack of a device that can accurately give the neutron radiation absorbed dose of plant seeds, the compact D-D neutron generator has limited its application in neutron radiation biological research and radiation mutation breeding.
