Characterization of optically stimulated luminescence dosemeters to measure organ doses in diagnostic radiology

Optically stimulated luminescence in synthetic quartz

Optically stiniulated luminescence (OSL). has been studied in synthetic quartz crystals. which had previously been exposed to Jtor X-irradiations. The main emission hands appeared at 380 and -~440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330nm. This maximum coincides with an excitation maximum of the phototransferred thermoluminescence (P...

Patient Effective Doses in Diagnostic Radiology

A Survey of Organ Equivalent and Effective Doses from Diagnostic Radiology Procedures

The quantification of radiation risks associated with radiological examinations has been a subject of interest with the increased use of X-rays. Effective dose, which is a risk-weighted measure of radiation to organs in the body associated with radiological examination, is considered a good indicator of radiological risk. We have therefore investigated patient effective doses from radiological ...

Optically Stimulated Luminescence Dating (Instrument Design for Mars Applications)

Introduction: To examine the geological and climatic history on Mars, we investigate an instrument design for robotic, in-situ, Optically Stimulated Luminescence dating (OSL). In this paper, we discuss the basic concepts of OSL, its benefits, and how this technique can be utilized on Mars. Also presented are the vital electronics needed for an instrument design and some of their basic operation...

applying optically stimulated luminescence to determine the slip rate of part of the baatar hyarhan fault in mongolia (central asia)

optically stimulated luminescence (osl) is currently one of the most important dating methods. it dates the last exposure to sunlight. natural hazard evidences such as colluvial wedges, alluvial and fluvial sediments can be dated by osl. therefore, osl plays an important role in studies related to paleoseismology and tectonic activity, particularly in arid and semi- arid regions. the altai moun...
