Two photon TL dosemeters based on LiF:Mg,Cu,P fixed onto cards are tested in order to compare their dosimetric performance. ENEA cards have been used as a routine since 1995 and they contain chips of GR200A (Solid Dosimetric Detector and Method Laboratory-SSDML, China), whilst cards by RADCARD have been commercially available only recently and they contain chips of MCP-N (made in Poland). The cards, which have the same dimensions, were both read out with a Harshaw 6600 Automated TLD reader, according to the reading cycle recommended by the manufacturer. A sample of 10 cards of the two types were compared on their performance relating to gamma-sensitivity, detection threshold, linearity, dose range, coefficient of variation, repeatability, and residual signal. Moreover, tests have been performed to evaluate their plastic resistance when heated at a temperature higher than 240 {ring operator} C. Results are reported and discussed.
