    • Abstract:
      The whole-body counting facility at the Indira Gandhi Centre for Atomic Research uses an in-house built Masonite cut-sheet phantom for the calibration of whole-body monitors. Recently, an Indian Adult BOMAB phantom was procured as an additional utility to augment the facility. The present study is to generate full-energy peak efficiencies (FEPE) of the shielded chair (SC) whole-body counting system using the new BOMAB phantom through Monte Carlo (MC) simulations. The values are compared with that of the Masonite phantom. First, the SC was modelled along with the Masonite phantom to estimate the FEPE values and Compton scattering factors (CSFs) for different energies. The simulated values were validated against the measurements using the Masonite cut-sheet phantom (Masonite phantom). The validated SC model was used along with the Indian adult BOMAB phantom to estimate the FEPEs and the CSFs. The simulated BOMAB phantom values were compared with the simulated Masonite phantom values. The maximum deviation for both the FEPEs and CSFs was ±10% validating the use of the Masonite phantom as a calibration tool representing an Indian adult.
