Summary: | The neutron and gamma spectra measurements have been made for benchmark iron spherical assemblies with the diameter of 30, 50 and 100
cm. The
252Cf neutron sources with different emissions were placed into the centre of iron spheres. In the first stage of the project, independent laboratories took part in the leakage spectra measurements. The proton recoil method was used with stilbene crystals and hydrogen proportional counters. The working range of spectrometers for neutrons is in energy range from 0.01 to 16
MeV, and for gamma from 0.40 to 12
MeV. Some adequate calculations have been carried out. The authors propose to carefully analyse the leakage mixed neutron and gamma spectrum from iron sphere of diameter 50
cm and then adopt that field as standard. |
