Abstract :
A new method for imaging and areal density determination of thin radioactive sources based on the detection of low-energy electrons emitted from the source surface is proposed. The feasibility of the technique was tested with a weak α-source. As an example of possible applications, the areal distribution of a 7Be radioactive source was measured, which is of importance for the “solar neutrino puzzle”.
