AN IN-SITU RELATIVE CALIBRATION FOR X-RAY FILM

An in-situ relative calibration technique for X-ray film is described in this paper. The technique is based on film exposure measurements which is irradiated by x-rays transmitted through a stepwedge absorption filter. The calibration method and the treatment method of data are given. Also, we present a characteristic curve for Kodak AA5 film obtained in an X-ray laser experiment.
