Refusable personal monitoring device

A device for recording and storing incident radiation energy from outside of the device and for reading said energy comprising, in order from the outside of the device where the incident radiation comes in:

• an outermost layer covering said device at a largest side of the device, said outermost layer being a filter layer which absorbs energy which is not to be detected during exposure of the device;
• a transparent layer;
• a storage phosphor layer comprising a stimulable phosphor which absorbs and stores said energy and is stimulable by a wavelength λa,
• a transparent electrode layer,
• an electroluminescent layer comprising an electroluminescent phosphor emitting, upon application of an electrical field, stimulation light with said wavelength λa,
• an isolating layer,
• a conductive layer,
• a carrier support layer, and
• at surrounding edges of each layer, a surrounding layer, which is an optical filter layer transmitting exclusively energy released by said storage phosphor layer upon stimulation of the stimulable phosphor,
• wherein said device includes means to apply an electrical field on said electroluminescent phosphor, and wherein said stimulable phosphor and said electroluminescent phosphor are positioned relative to each other so that said light emitted by said electroluminescent phosphor reaches said stimulable phosphor to stimulate said phosphor to release stimulated light as a detectable signal.
