A method for measuring the activity of high-intensity radioactive sources via registration of innerbremsstrahlung spectra was developed. Equations that connect the spectrum shape to the activity of different parts of a source and to the γ activity of background impurities were obtained. A technique was developed that allows unambiguous elimination of the detector influence on spectral measurements. A procedure for modeling the passage of γ radiation through the source substance and protection is described, and the calculation of the germanium-detector response functions, which was performed with the Monte Carlo method using the Geant4 package, is presented. The developed method can be used for independent measurements of the activity of neutrino sources of the 51 Cr and 37 Ar type as an alternative to calorimetric measurements.

“…37 Ar sources have been used as a check source for neutrino experiments [1,2,3] because of the almost monoenergetic neutrino emitted during the decay to 37 Cl. The 37 Ar samples produced through the irradiation of natural argon gas at The University of Texas at Austin were used to assist in the calibration of an ultra-low-background proportional counter [4].…”

The production of radioargon through the irradiation of CaO was performed in an in-core facility within the The University of Texas at Austin MARK II TRIGA reactor. The major radioargon isotope produced was 37 Ar via the 40 Ca(n,α) 37 Ar reaction pathway. The CaO powder was vacuumed sealed in a quartz ampoule. The sample was irradiated in a Cd-lined Al alloy canister for 2 hours at 500 kW. After the irradiation, the sample was counted using an HPGe detector five times with increasing count times. 41
