Gamma-ray attenuation properties of some NLO materials: potential use in dosimetry.

Gamma-ray attenuation properties of some NLO materials: potential use in dosimetry. Radiat Environ Biophys. 2019 Nov 28;: Authors: Al-Buriahi MS, Singh VP, Arslan H, Awasarmol VV, Tonguc BT Abstract Mass attenuation coefficients ([Formula: see text]) for some nonlinear optical materials such as potassium dihydrogen phosphate, ammonium dihydrogen phosphate, zinc tris-thiourea sulphate, and zinc thiourea chloride were measured using a [Formula: see text] NaI(Tl) scintillation detector at gamma energies of 122 keV, 356 keV, 511 keV, 662 keV, 840 keV, 1170 keV, 1270 keV, and 1330 keV. In addition, GEANT4 simulations were carried out to mimic the experiment at these energies. As a result, good agreement between the experimental and GEANT4 results was observed. The measured [Formula: see text] values were used to compute effective atomic numbers ([Formula: see text]) for the selected materials. It was found that the [Formula: see text] values were in the range typical for dosimetric materials. PMID: 31781839 [PubMed - as supplied by publisher]
