Construction of detector is necessary. However, on large energy range the manufacturers could not also support the explicit function of relative and absolute efficiencies of detectors. One of the reasons is a restriction of energy range of gamma sources (normally < 3 MeV). This paper presents the results of construction of relative and absolute efficiency functions within a range from 122 keV to 8.5 MeV. The sources are used combining 152Eu point source and 36Cl activated isotope by thermal neutron captured reaction 35Cl of Dalat nuclear reactor (DNR) by 35Cl(n, γ)36Cl reaction. This result can be applied in determining quantitative analysis of samples of neutron activation and radioactivity chemistry
