The method of choice for isotope detection in digital autoradiography is the Image Plate^TM (IP) technology. Imaging Plates is a reusable two-dimensional sensor for the detection and storage of ionizing radiation energy found in photo-stimulable phosphors, which consist of a complex matrix of BaFX:Eu²+ (X: halogen) crystals.
There are IPs for virtually any type of emitter, all with superior accuracy.
Due to the unmached sensitivity, the high dynamic range of linear response to the signals, the IP-technology delivers most accurate data in quantitative experiments. Frequently, IP technology is used for Southern and Northern Blot detection, array technology, histology and other techniques with needs for highest sensitivity.

• reuseability of imaging plate, no film development necessary
• dynamic range 5 orders of magnitude
• linearity 5 orders of magnituden, digital data
• direct acess to software evaluation
• sensitivity relative to film10-1000 times more sensitive, depending on energy of emmitters
• examples for absolute sensitivity:
