Calibration coefficients for the PPT detector using the 60Co and 40K lines: E=0.5514*ch - 83.322. Internal radioactivity at 1444 keV, not separated from 40K
Efficiency: During the run (21h46min40s) the number of gammas emitted from the 60Co source is 66796800; for the Co pics the integrals are: 2.71e05 for the 1173.2 and 1.87e05 for the 1333, respectively (0.4% and 0.3%) without geometrical factor |
