Description

The dark and light current-characteristics of Xeroradiographic plates have been considered by the theoretical and preliminary experimental investigation.<br/> The relations between the surface potential on the plates and the dv/dt in a dark decay curve have approximately indicated an exponential curve. Therefore, an RC model cannot fit to it.<br/> The X-ray decay characteristics of Xeroradiographic plates in X-ray radiation are disclosed as follows: <img align="middle" src="./Graphics/abst-eq1_4_1_3.png"/>, <br/>where E is the X-ray energy, φ is X-ray density, β is the X-ray energy absorption coefficient, L is the thickness of selenium film, μ is the mobility of carrier and F(t) is the factor to time in which the effects owing to trapping carriers, recombination of carriers and radiation of secondary electrons have been included.<br/>Results are that the photosensitivity in X-ray radiation has proportionately increased with the thickness of selenium film and X-ray energy absorption coefficient and X-ray dose rate.
