Evaluation of a standardization method for 22Na sealed point sources for various measurement conditions

We have devised a standardization method for a sealed point source that can be applied to nuclides such as 22 Na that emit a positron and at least one gamma ray. This method is based on coincidence counting of annihilation radiation and gamma rays using a scintillation detector array. In the present...

Description
Summary:We have devised a standardization method for a sealed point source that can be applied to nuclides such as 22 Na that emit a positron and at least one gamma ray. This method is based on coincidence counting of annihilation radiation and gamma rays using a scintillation detector array. In the present study, we performed Monte Carlo simulations to examine this method for various measurement conditions. EGS5 Monte Carlo simulation results confirm that this method is effective for measurements of a 22 Na sealed point source using BGO scintillation detector arrays.
