Study of a new glass matrix by thermoluminescent technique for high-dose dosimetry

Brazilian Journal of Radiation Sciences, 2017
The thermoluminescence technique is widely used for both personal and high-dose dosimetry. In this work, the thermoluminescence technique was utilized to study a new glass matrix, with nominal composition of 20Li2CO3.10Al2O3.30BaO.40B2O3 (mol ...

Hand monitoring in nuclear medicine departments in Croatia - first results [PDF]

Nuclear Technology and Radiation Protection, 2020
Individual hand monitoring for workers who manipulate unsealed radioactive sources in nuclear medicine is a necessity and the results can serve as the base for optimization processes. We performed an analysis of individual hand doses for medical

Areal dosimetry at research centres [PDF]

, 2017
Radiation protection regulations apply to research centres and nuclear facilities alike. Radiological dose resulting from their activities is strictly limited by law; therefore, it has to be monitored.

Tb3+‐Doped Glass‐Ceramic Scintillating Plates and Fibers for X‐Ray Imaging and Flexible Detection

Advanced Science, EarlyView.
A Tb3+‐doped glass‐ceramic scintillator, with controlled Ba2GdF7 nanocrystal precipitation, was developed through a rational design strategy guided by phase diagrams and molecular dynamics simulations. The obtained material exhibits a high light yield of 41 800 photons/MeV (418%/BGO), a spatial resolution of 25.3 lp/mm, and exceptional thermal ...
