Abstract
Four groups of grain sizes of LiF:Mg,Cu,P material were chosen for the experiment. The influences of the grain size on the photon energy response and dose response have been examined in the interval of 28-1250 keV and the dose range 0.1-30 Gy of 60Co gamma -rays. The experimental results show that both the energy response and the dose response are grain size dependent. A possible correlation seems to exist between the energy response eta (E) and the dose response f(D). A brief discussion is provided.
