background: advances in radiation dosimetry concepts and the development of primary measurement standards based on absorbed dose to water over the last decades offer the possibility to calibrate ionisation chambers directly in terms of absorbed dose to water. the aim of this study is the investigation on utility of artificial body fluid (abf) instead of water by comparing dosimetric measurement...

– gafchromic xrct radiochromic film is a self developing high sensitivity radiochromic filmproduct which can be used for assessment of delivered radiation doses which could match applications suchas computed tomography (ct) dosimetry. the dose response of gafchromic xrct radiochromic film hasbeen measured with reflectance spectrophotometry and desktop scanners. the film automatically changescol...

in order to improve the performance of a newly developed radiochromic film, gic-79, somedosimetric characteristics of this film have been studied based on relevant standard practice. the presentstudy describes some parameters that may affect the dosimeter response before, during, and after irradiation. the effect of absorbed dose rate on dosimeter response was determined by irradiating dosimete...

background: the human body contains of different tissues and cavities with different physical and radiological properties. most important among these are tissues and cavities that are radiologically different from water, including lungs, sinuses and bones. gel dosimetry provides a unique feature to display dose distributions occurring in clinical radiation therapy in three dimensions. materials...

OBJECTIVE To summarize the research progress about the dosimetry and biological predictors of radiation-induced esophagitis. METHODS We performed a systematic literature review addressing radiation esophagitis in the treatment of lung cancer published between January 2009 and May 2015 in the PubMed full-text database index systems. RESULTS Twenty-eight eligible documents were included in th...

The application of pulsed radiation fields for research, security screening and medical examinations has increased remarkably in the last years. Testing of active personal and area dosemeters for the operation in pulsed radiation fields is a necessity to judge the suitability of the dosemeter. Up to now, radiation protection dosemeters have only been tested in continuous fields, although they a...
