AI4R offers a very high performance system in real time digital autoradiography. Thanks to its intrument range, the BeaQuant and the BeaQuant-s, every radioisotope can be used to realize quantitative picture of the radioactvity. With a field of view up to 20x20 cm², the very high verstility and the spatial resolution of 20µm BeaQuant range allows a perfect image reconstruction of any kind of radioactive samples. The very high sensitivity increases the power of seeing very weak labelling.
