title: The standfast whole body counter and the sliced BOMAB phantom: efficiency as a function of number of sources and energy modeled by MCNP5.
abstract: Previously, using Monte Carlo simulations, this laboratory conceptualized a new phantom: the sliced Bottle Manikin Absorber (BOMAB) phantom. It was intended for calibration or performance testing of whole body counters and the HML subsequently built and tested that phantom. Also, this laboratory tested another phantom used for the calibration of the StandFast whole body counter and identified some deficiencies. This paper investigates the use of the sliced BOMAB phantom as an alternative for the calibration of the StandFast and shows how the 165 sources required for a full loading of the sliced BOMAB can be reduced to a much smaller number without compromising the calibration. The agreement of the sliced BOMAB with eight sources is approximately 1% when compared with a conventional BOMAB phantom.
