(4) Storage Phosphor Imaging Screens
Bio-Rad offers a range of storage phosphor screens to match different user requirements.
Table 2.1 summarizes the key features of each screen. The screens are composed of a
barium fluorobromide matrix doped with europium (BaFBr:Eu); they can be used with
traditional autoradiography cassettes without a darkroom, are easy to handle and are used
solely for the detection of isotopic emissions.
PharosFX Plus offers a variety of phosphor storage applications in addition to all the
functionality of the PharosFX. All phosphor screens are reusable and unharmed by repeated
exposure to radioactivity. Screens are sensitive to
β
particles and X-rays. All screens are
flexible and easy to handle. Exposure takes place in standard X-ray cassettes. All phosphor
screens require erasure prior to re-exposure, and their lifetime is extended when they are
cared for properly.
