Abstract

The invention discloses a The invention discloses a 252Cf source distribution irradiation device used for plant seed neutron irradiation. The 252Cf source distribution irradiation device comprises a cylindrical shielding body, an air channel, a 252C neutron source, and sample irradiation areas. The high neutron yield of the 252C neutron source meets the requirements of the neutron irradiation plant seeds, and at the same time, by taking the 252C neutron source as a sphere center, three semispherical areas having sequentially increased radiuses are used as the sample irradiation areas. The seeds having ant neutron absorption doses can be acquired according to gradients, and the absorption doses of the seeds of every gradient are uniform. The plant seed absorption doses of the three252Cf neutron source doses distribution semispherical areas are directly provided without tedious measurement and calculation, and therefore a standardized dose distribution characteristic is provided, and most of leguminous plant seed neutron irradiation scientific research requirements are satisfied, and the irradiation device can be used for irradiation of other types of plant seeds, and also can be used for neutron irradiation agricultural production and mutagenic breeding.

Description

technical field [0001] The invention belongs to the technical field of plant seed breeding, in particular to a neutron irradiation device for plant seeds 252 Cf source dose distribution irradiation device. Background technique [0002] Irradiating plants will cause radiation biological effects in plants and induce plant mutations. Among them, the technology of irradiating plant mutations is one of the important means and ways to speed up the breeding process and obtain excellent varieties. In the early days, photon technologies such as X-rays, γ-rays and lasers were mainly used to carry out research work on radiation biological effects and radiation mutation breeding, and many achievements have been made in the cultivation of new varieties of crops and ornamental plants. Since the 1980s, the breeding technology of charged particle irradiation has also developed rapidly in my country. In recent years, more and more researches on irradiated plants have been carried out by usi...
