The background spectrum of a 3 ″× 3 ″NaI (Tl) well-type scintillation SILENA detector was
measured without shielding, in 6 cm thick lead shielding, and with 2 mm thick electrolytic …

The absolute total detection efficiency of a detector for gamma rays intensely depends on
the solid angle subtended by the detector's front surface at the gamma source. In the present …

Alloys of the type Pb 60 Sn 20 Zn x Cd (20-x) where x= 0, 5, 10, 15 or 20 were prepared by a
conventional melt quench technique. The intensity distribution of backscattered photons …

In this research, we studied the graded shielding using one of gamma-ray spectroscopy
techniques, which consists of a scintillation detector sodium iodide activated by thallium NaI …

[en] The background-reduction shielding system in nuclear analysis systems helps to reduce
the influence of gamma rays not released from the sample on the measured results …
