Apparatus for detecting and locating a radioactive source emitting gamma rays and use of said apparatus
First Claim
1. An apparatus for detecting and locating a radioactive source emitting gamma rays, comprising:
- gamma-ray sensor;
a plurality of measuring means capable of receiving a light signal emitted by the sensor;
analyzing means for comparing signals output by the measuring means in order to determine a direction in which the source is offset with respect to a detection axis;
means for defining a central axis of the apparatus; and
means for imparting a movement to the apparatus in response to movement instructions as long as the analyzing means indicate that the central axis of the apparatus is not in correspondence with the source.
