Abstract
Backscattering peak is one of the main features of the pulse height spectrum from a gamma ray detector. This arises mainly from materials outside like source baking, photomultiplier tube housing, shielding etc. The effect of source backing on the relative importance of the backscattered peak for gamma ray using a NaI (Tl) scintillation detector is measured. Gamma energies in the range from 0.088 MeV to 1.253 MeV are used. Backscattering factor (Fb) measurements have been carried out (2 > Fb ≥ 1) of various pure concrete thickness from 2 cm to 30 cm.
