Use of XR-QA2 radiochromic films for quantitative imaging of a synchrotron radiation beam [PDF]
, 2015 This work investigates the use of XR-QA2 radiochromic films for quantitative imaging of a synchrotron radiation (SR) beam. Pieces (200 7 30 mm2) of XR-QA2 film were irradiated in a plane transverse to the beam axis, at the SYRMEP beamline at ELETTRA ...

Study on a New Label Dosimeter for Radiation Processing
Journal of Isotopes, 2016 In order to monitor the absorbed dose of goods in 60Co γ-rays and electron beams, a new label dosimeter had been developed for dose measurements. The label dosimeter had a multilayer structure, and the core of which was a layer of radiochromic film.

Small fields measurements with radiochromic films
Journal of Medical Physics, 2015 The small fields in radiotherapy are widely used due to the development of techniques such as intensity-modulated radiotherapy and stereotactic radio surgery. The measurement of the dose distributions for small fields is a challenge. A perfect dosimeter should be independent of the radiation energy and the dose rate and should have a negligible volume ...

Optimization of radiochromic film stacks to diagnose high-flux laser-accelerated proton beams.
Review of Scientific Instruments, 2020 Here, we extend flatbed scanner calibrations of GafChromic EBT3, MD-V3, and HD-V2 radiochromic films using high-precision x-ray irradiation and monoenergetic proton bombardment. By computing a visibility parameter based on fractional errors, optimal dose

Radiochromic film for medical radiation dosimetry [PDF]
Materials Science and Engineering: R: Reports, 2003 Abstract Photon, electron and proton radiations are used extensively for medical purposes in diagnostic and therapeutic procedures. Dosimetry of these radiation sources can be performed with radiochromic films, devices that have the ability to produce a permanent visible colour change upon irradiation.
