For the case of radiation emergency, it is required to assess internal contamination of the public, including childrenas well as adults. The objective of the present study was to assess counting efficiency of a whole body counter by humanbody size and standing position of the measurement person. In this study, the FASTSCAN whole body counter used atNational Radiation Emergency Medical Center of Korean Institute of Radiological and Medical Science was simulated by aradiation transport computer code. The simulation results of the counting efficiencies agreed well with measurements withinthe 2% of discrepancy for 4-year child and 5% for adults. The standing positions of the people were adjusted by body sizeto find the consistent trend of the counting efficiencies by human body size. Body size scaling factors of the whole bodycounter were derived to consider human body size and improve the measurement accuracy. The counting efficiencyassessment methodology in this study can be successively used to improve the measurement accuracy when using a wholebody counter for the case of radiation emergency.
