Abstract
The current partial-body counter installed at KIT is under redesign in order to add whole-body counting capabilities and to replace the current phoswich detectors with HPGe detectors, also able to detect low energy photons (210Pb, 241Am). Dierent configurations for the positioning of the subject have been tested with the aid of Monte Carlo simulations and the performances attainable with a sitting and a lying configuration were compared. The optimal placement of the detectors was also defined. The simulations were used not only to estimate the counting eciencies, but also to estimate the Compton scattering produced by 40K, then used to calculate the minimum detectable activities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
