Monte Carlo calculation of response functions to gamma-ray point sources for a spherical NaI(Tl) detector

Response functions of a 7.62 cm-diameter spherical NaI(Tl) detector to gamma-ray point sources in the energy range up to 1.5 MeV were calculated by means of the Monte Carlo method using PENELOPE-2006 (Salvat et al., 2006). The detector materials and dimensions were modeled realistically. The calculated response functions agreed well with the experimental spectra.

► Response functions of the spherical NaI(Tl) detector for the 4 point sources were calculated using the Monte Carlo method.
► Simulation code PENELOPE-2006 was used in the calculation.
► Comparison of calculation results with experiments was made.
► Calculated response functions agreed well with the experimental spectra.
