ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

This work aims to investigate major operation parameters including scan uniformity, film orientation, scan resolution, image region of interest, energy dependence, postirradiation coloration, and ambient temperature in order to establish an appropriate protocol for calibration and dose measurement using a GafChromic film dosimetry system. A two-dimensional dosimetry system comprising GafChromic films and an Epson Expression 1680 flatbed document scanner was employed. EBT films in a 30- × 30- × 25-cm3 solid water phantom were exposed in a photon field delivered by a Varian 21EX electron linear accelerator with a 10- × 10-cm2 field size. The operation parameters of the GafChromic film dosimetry system were investigated in detail. The dose profile measurement was compared with calculation delivered by the Varian Eclipse treatment planning system. Some deviations in the penumbra regions were found.
