20200041668 · 2020-02-06 ·

A method and system for directional radiation detection. Two or more radiation detectors are attached to a user's body and the body acts to attenuate radiation passing through the body, such that radiation striking a detector without first passing through the body has a greater intensity than radiation striking a detector after passing through the user. Intensity differences between radiation received at different detectors is thereby used to determine a direction from the user to the radiation source.
