| Summary: | 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. |
