The analysis of the measurement uncertainty with application of small detectors made of Gafchromic EBT films for the range of doses typical for in vivo dosimetry in teleradiotherapy

The Gafchromic EBT films have sufficient accuracy for dose measurements above 20 cGy and may be an interesting alternative for the semiconductor or thermoluminescent detectors as an in vivo dosimeter. Contrary to these detectors Gafchromic EBT films are transparent for radiation.
