PROBLEM TO BE SOLVED: To thoroughly erase a CsBr:Eu type binderless needle-shaped photostimulable phosphor in a storage phosphor screen in order to avoid loss of image quality which may be caused by undesirable emission interacting with a signal detected after reading a storage phosphor plate. SOLUTION: A method of reading a radiation image stored in a CsBr:Eu type binderless needle-shaped photostimulable or storage phosphor screen after X-ray exposure of the screen, comprises the steps of: (1) erasing thermally stimulable energy by exposing the screen to infrared radiation in the wavelength range of 1,000-1,550 nm; (2) stimulating the phosphor screen by means of stimulating radiation in the range of 550-850 nm; (3) detecting light emitted by the phosphor screen upon stimulation and converting the detected light into a signal representation of the radiation image; (4) erasing the phosphor screen by exposing it to erasing light in the wavelength range of 300-1,500 nm.
