Angular dependence Figure 3 shows the measured angular dependence of the detection efficiency for the gamma rays from the 137Cs and On request I present a short demo of my gammaspectrometry hardware used with Theremino MCA 5.0 running on a Mac Mini / Windows 7. The internal soundcard is u The barium precipitate is filtered and the Ra-226 is counted by alpha spectroscopy. Barium-133 (Ba-133) is used to quantify the yield by gamma spectroscopy.

Please note that these constants are for individual radionuclides only and not for decay series (e.g., U-238 plus progeny; Th-232 plus progeny, Ra-226 plus progeny, etc.) This research proposes a production method using a high-energy photon spectrum (generated by a linear accelerator or LINAC) to irradiate a sample of Radium-226 (half-life 1600yrs). The photo-neutron reaction liberates neutrons from Ra-226 atoms leaving behind Radium-225 (half-life 14.7 days). Ra-225 decays naturally through beta emission to Ac-225. The gamma radiation spectrum was analyzed to determine the concentrations of specific radionuclides (40K, 228Ra, 226Ra,238U and 232Th) in Bq/L. Chemical analyses were performed at the Hydroche-mistry Lab of the University of Belgrade Faculty of Mi-ning and Geology to define hydrogeochemical condi-tions and determine groundwater types.
