Dosimetric characteristics of fabricated Ge-doped silica optical fibre for small-field dosimetry

Results in Physics, 2019
We study 3 mm long germanium-doped (Ge-doped) silica fibres for small-field dosimetry, seeking to overcome spatial resolution and charged-particle disequilibrium issues, also any associated dose deviation from that of computerised treatment plan dose ...

Operational comparison of bubble (super heated drop) dosimetry results with routine albedo thermoluminescent dosimetry for a selected group of Pu-238 workers at Los Alamos National Laboratory

, 1998
This paper is an operational study that compares the use of albedo thermoluminescent dosimeters with bubble dosimeters to determine whether bubble dosimeters do provide a useful daily ALARA tool that can yield measurements close to the dose-of-record.

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 DOSIMETRY OF BETA DEPTH DOSE [PDF]

American Journal of Roentgenology, 1966
Radiothermoluminescent measurements have been made of Y90 beta depth dose from a commercially available Sr90-Y90 beta applicator. Good agreement of the resulting beta depth dose curve with those obtained by film and extrapolation chamber techniques of measurement suggests the usefulness of radiothermoluminescent dosimetry as a rapid and convenient ...
