Studies of decay radiations subsequent to neutron irradiations is a well known technique of isotope analysis. Also, well known is the production of radioactive materials for medical imaging and therapy purposes. The Saskatchewan Research Council's SLOWPOKE-2 reactor is a well established facility. We intend to use this facility to determine the concentrations of rare earth materials (Nd, Sm, ..) by characteristic photons of products of neutron irradiaton. However, neutron energy spectrum of this facility, an important piece of information required to determine the products of irradiation is not known. Our preliminary measurements of Summer 2010 revealed that there is a significant component of fast neutrons as high as 9 MeV energies are present.

中子辐照后衰变辐射的研究是一种众所周知的同位素分析技术。同样，众所周知的是用于医学成像和治疗目的的放射性材料的生产。 萨斯喀彻温省研究理事会的SLOWPOKE-2反应堆是一个完善的设施。 我们打算使用该设备来确定稀土材料（Nd，Sm，.）由中子辐照产物的特征光子决定。 然而，该设施的中子能谱（确定辐射产物所需的重要信息）尚不清楚。我们对2010年夏天的初步测量表明，存在能量高达9 MeV的快中子的重要组成部分。
