Evaluation and Comparison of Entrance Skin Dose in the Imaging of Hip Region Using Computed Tomography (CT) Scan and Stereoradiography

مجله دانشکده پزشکی اصفهان, 2019
Background: Extensive use of computed tomography (CT)-scan imaging is associated with an increase in cumulative dose. Stereoradiography by electro-optical system (EOS) is an X-ray imaging technology that can reduce patient absorption dose, and increase ...

Thermoluminescent composites of sintered synthetic-topaz/in situ corundum for dosimetry by a novel reversible process

Heliyon
Topaz (Al2F1·44(OH)0·56SiO4)/corundum (Al2O3) composites were prepared by a facile and novel reversible process from the sintering of synthetic topaz and AlF3 powders, with corundum formed in situ into the topaz matrix.

Thermoluminescence dosimetry in the Caribbean.

The West Indian medical journal, 2003
The results of five years of radiation monitoring of 590 radiation workers in Jamaica and an additional 88 in Barbados and The Turks and Caicos Islands show that the annual dose absorbed by Caribbean radiation workers is, with a single exception, well within the internationally accepted limits of 20 mSv per year. There were few cases of relatively high
