One dimensional water phantom for absolute measurements according to AAPM TG-51 and IAEA TRS-398 dosimetry protocols.

The phantom has been designed for absolute dose measurements in radiation beams with horizontal beam incidence. Furthermore it is suitable for the calibration of ionization chambers used in radiation therapy. The phantoms’ design allows cross calibration of a field ionization chamber against a calibrated reference chamber at the user’s facility. The phantom has engraved crosshairs, two handles for easy carrying and a drain tap for emptying without changing the phantom’s position. Various adapters for ionization chambers and FeSO4  dosimeters are available.

The phantom has an advanced configuration with continuous fine depth adjustments by using linear scale. The measuring depth is adjustable either from 18 mm up to 250 mm for cylindrical chambers or from 8 mm (respectively 12 mm depending on chamber type) up to 250 mm for parallel plate chambers.
