The newly developed two-dimensional thermoluminescence (TL) foils made from CaSO 4 :Dy TL powder and the high temperature polymer PFA, were tested for their dosimetric properties. The results were evaluated using laboratory TL reader with PCO CCD camera and round planchet heater, 72mm in diameter. 55×55×0.3mm 3 foils were tested for dose response, reproducibility and spatial resolution. It was found that the detectors are linear up to at least 2Gy and their spatial resolution is about 1mm. A loss of sensitivity with repeated re-uses was observed (9% in 10 uses). It is attributable to the darkening of the detector due to oxidizing of impurities gathering at its surface and may be avoided by application of proper cleaning procedure. The foils were tested for measurements of 2-D dose distribution on 60MeV proton beam at IFJ Krakow. The results show that 2-D TL foils based on CaSO 4 :Dy can be a useful tool for quality assurance of proton beams.
