The present work describes use of a water-equivalent radio-fluorogenic gel dosimeter for
measurement of a depth dose distribution from a medical linear accelerator. Relative depth
dose distributions for a 6 MV photon beam were measured with a novel radio-fluorogenic

Abstract
The present work describes use of a water-equivalent radio-fluorogenic gel dosimeter for measurement of a depth dose distribution from a medical linear accelerator. Relative depth dose distributions for a 6 MV photon beam were measured with a novel radio-fluorogenic gel comprised of aqueous gelatin and coumarin-3-carboxylic acid. Agreement was within 3 % of published values in most areas of electronic equilibrium. Results support continued development of radio-fluorogenic gel dosimetry systems for quality assurance of clinical photon beams.
