Gafchromic EBT-3 is designed for the measurement of absorbed doses of ionizing radiation. It is particularly suited for high-energy photons. The dynamic range of this film is designed for best performance in the dose range from 0.2 to 10 Gy, making it suitable for many applications in IMRT, VMAT and brachytherapy. For measurement of doses substantially greater than 10 Gy EBT-XD or MDV3 are preferred while the use of HD-V2 is indicated for still higher dose measurement.

It comes in different packing’s and cuts including 8X10 and 14X17 sizes.

Key technical features of GAFChromic EBT3 include:
• Dynamic dose range: 0.1 Gy to 20 Gy
• Optimum dose range: 0.2 Gy to 10 Gy, best suited for applications such as IMRT and VMAT
• Develops in real time without post-exposure treatment;
• Energy-dependence: minimal response difference from 100keV into the MV range;
• Near tissue equivalent;
• High spatial resolution – can resolve features down to 25μm, or less
• Proprietary new technology incorporating a marker dye in the active layer:
• Enables non-uniformity correction by using multi-channel dosimetry
• Decreases UV/visible light sensitivity
• Stable at temperatures up to 60°C
