Abstract
The invention provides improved methods and apparatus for investigating emissions from radioactive sources within an environment. In particular, the method deploys a collimated detector to scan the environment and obtain approximate position information on sources within that environment together with further investigations using a moveable shielding component which is moved relative to the field of view of the collimator. In an alternative technique, the collimator is moved in two different directions to achieve positional information using scanning.
