Gafchromic EBT 2
A new generation of self-developing dosimetry film with performance features that surpass the original technology called GAFCHROMIC EBT2, its advanced technology retains all of the attributes that make the original film easy to use in a radiotherapy environment, but now includes a marker dye to support automated calculations of dose response using both the red and blue color channels of a flatbed color scanner. The new film represents an improvement over GAFCHROMIC EBT in the area of uniformity because the response value derived from the marker dye provides a reference level for the performance of the film.

• Measure with an economic flatbed color scanner
• Dose range 1cGy – 10Gy (measure in red color channel); up to 40Gy measured in green color channel
• Develops in real time. There is no post-exposure treatment
• Density changes stabilize rapidly after exposure
• Energy-dependence: <10% response difference from 60keV into the MV range
• Near tissue equivalent
• High spatial resolution – can resolve features to at least 100µm
• Handle in room light – eliminate the need for a darkroom
• Can be cut to any size and shaped to contours
• Water resistant – Can be immersed for hours in water phantoms
• Stable at temperatures up to 60°C
• GAFCHROMIC EBT2 is available in two formats:
  - EBT2 810: 8” x 10” in size, 25 sheets/box
  - EBT2 1417: 14” x 17” in size, 10 sheets/box
