    摘要: In a method of determining the cumulative exposure dose as captured by an adapted radiation capturing means therefor, said method comprises the steps of determining the average time lapse between exposure and read-out from ratios of read-out signals after photostimulation or thermostimulation of at least two storage phosphors and calculating the cumulative exposure dose therefrom, provided that said storage phosphors are differing in dark-decay rate.
