Abstract
Improved efficiency and spatial resolution are obtained without collimators or ionizable media by a locating system in which radioactive sources to be located are disposed within an electric field sufficient to force radio-emitted charged particles directly towards an oppositely charged electrode without appreciable scattering. In one aspect, the two oppositely charged electrodes are separated at a distance that avoids arcing. In other aspects, dielectric materials may be disposed between the electrodes, and the area between the electrodes can be evacuated.
