| Abstract: | The counting yield for large volume, complex geometry samples such as solutions in Marinelli beakers as counted on a large
NaI(Tl) detector can be calibrated using radionuclides activated by neutrons form a252Cf source. Calibration may be done by using either a known neutron flux facility or by cross calibration of the activated
material as a point source vs. sealed gamma-standard sources. The point source of activated material is dissolved after cross
calibration to produce the large volume distributed source. |
