Dose-Map™ dosimetry system
Chemistry: Advanced Materials
The Dose-Map film cassette system is easy to use for verification of a blood irradiator’s performance. It is used to measure and map the absorbed dose in the blood irradiator canister and has a typical accuracy of plus or minus 5 percent, based on calibrated doses provided by the University of Wisconsin Radiation Calibration Laboratory.
The Dose-Map cassette is exposed using a standard irradiation cycle. After the exposed cassette is returned to Ashland, the film is analyzed using a flatbed scanner and software designed specifically for film dose analysis. All measurements are indexed to alanine, an internationally recognized dosimetry transfer standard. The measurement of the alanine pellet is performed by the National Institute of Standards and Technology.
Information provided to the customer consists of:
- a color-coded dose contour plot showing the distribution of absorbed dose in the canister, and
- a dose distribution chart showing the centerline, left edge and right edge of the canister.
