利用医用回旋加速器产生的以~(13)N-NH3形成赋存的气态~(13)N核素，成功地实现了NaI探测系统对MB形探测容器内正电子衰变气体源的效率刻度，并与应用Mone Carlo计算的理论值取得较好符合，解决了反应堆一回路~(13)N监测仪难以进行效率因子刻度的难题。

The PET Cyclotron was used to produce gaseous 13N positron emission nuclide that existed as 13Nammonia. The efficiency calibration of NaI(Tl) scintillation crystal detector for Marinelli Beaker filled with gaseous β+ radionuclide were achieved successfully, which expected to solve the problem of the efficiency of 13N monitor for inspecting leakage of Reactor coolant that hardly to get on the spot. The experimental values were in agreement wit...
