建立4～7MeV高能γ射线参考辐射是“十五”国防计量重点科研项目之一。4～7MeV能区高能γ射线参考辐射可为反应堆、加速器等所使用的监测仪表提供准确的效率及响应校准,在核能及军事科研领域有着重要意义。 该项目从2001年开始,预计4年完成。2001年,课题组在已有课题方案的基础上进行了进一步充分调研,确定了加速器监测系统的设计方案,为今后参考辐射建立及维护确立了基础,并在已有的设备条件下,对5SDH-2加速器19F（p,αγ）16O核反应产生的6～7MeVγ射
The establishment of 4 ~ 7MeV high-energy γ-ray reference radiation is one of the key scientific research projects of national defense measurement in the “Tenth Five-Year Plan” period. The high energy γ-ray reference radiation of 4 ~ 7MeV energy range can provide accurate efficiency and response calibration for monitoring instruments used in reactors, accelerators and the like, and is of great significance in the field of nuclear energy and military research. The project started in 2001 and is expected to be completed in 4 years. In 2001, the research group conducted further research on the basis of the existing research projects, determined the design scheme of the accelerator monitoring system, established the foundation for the establishment and maintenance of reference radiation in the future, and analyzed the 5SDH -2 accelerator 19F (p, αγ) 16 ~ 7MeV γ-rays generated by the nuclear reaction
