CyberKnife is one of multiple modalities for stereotactic radiosurgery (SRS). Due to the nature of CyberKnife and the characteristics of SRS, dose evaluation of the CyberKnife procedure is critical. A radiophotoluminescent glass dosimeter was used to verify the dose accuracy for the CyberKnife procedure and validate a viable dose verification system for CyberKnife treatment. A radiophotolumines...

Radiation dosimetry has the purpose of quantifying dose received by occupationally exposed individual. The device used in this process is called a dosimeter, dosimeter can be different situations, for example, to quantify fingers ring model extremity, which focus work. In Brazil, we still do not have standards calibration extremity dosimeters, therefore, work, CASEC recommendations were used, a...

The aim of this paper is to examine the energy and angular responses thermoluminescent (LiF:Mg,Ti LiF:Mg,Cu,P) optically stimulated luminescent (Al2O3:C) dosimeters with experimental measurements Monte Carlo simulations. Nine radiation qualities, mean energies ranging from 33 keV 1.25 MeV, five angles incidence, between 0? 80?, were used conduct analysis. IEC 62387:2020 international protection...

background: interventional cardiology procedures such as coronary angiography (ca) and percutaneous transluminal coronary angiography (ptca) has been increased recent years. the purpose of this study was to measurement of effective dose to cardiology staffs who operate near the patient and are exposed to non-uniform radiation field due to patient scattered radiation. materials and methods: this...
