[Study of a new commercial film for high energy photon dosimetry].
Dosimetric properties of a new film, the Extended Dose Range-EDR2, manufactured by Kodak, have been studied. We have established the response of the film versus dose and compared it with that of X-OMAT V films. We found a linear response with dose, for the range from 0.5 to 4 Gy. No dependence of this curve with beam quality and with depth is observed. EDR2 films are useful for dosimetric study of high-energy photon beam, especially when high dose gradient occurs such as for Intensity Modulated Radiotherapy Treatment.
