一辐射源农业上常用的辐射源有伽玛(γ)射线、爱克斯(x)射线、贝塔(β)射线和各种中子等,其中以中子诱变效率最高,贝塔射线次之,伽玛射线和爱克斯射线低于中子和贝塔射线。但由于射线来源、设备条件和安全等因素所限,目前最常用的是伽玛射线和爱克斯射线。伽玛射线(也叫丙种射线):是原子核内的电磁辐射,由原子核蜕变时产生的。它的波长短、穿透力强、射程远,因此一次可以照射 A radiation source commonly used in agricultural radiation sources are gamma (γ) ray, X-ray, beta (beta) rays and various neutrons, of which the highest efficiency of neutron mutagenesis, followed by the beta radiation, gamma Ma-ray and X-ray lower than neutron and beta radiation. However, due to the source of radiation, equipment conditions and safety and other factors, the most commonly used is the gamma ray and X-ray. Gamma rays (also known as gamma ray): is the electromagnetic radiation inside the nucleus, produced by the nuclei metamorphosis. It’s short wavelength, strong penetration, long range, so once can be irradiated
