Radiation mapping system
First Claim
1. A radiation detection and mapping system, comprising:
- means for detecting radiation from sources of radiation within a restricted solid angle;
means for shielding said means for detecting radiation so that incident radiation is substantially uniformly attenuated over all directions other than the restricted solid angle, said means for shielding having a substantially uniform thickness when measured from points along a central axis of symmetry of said means for detecting radiation;
means for determining the distance between the means for detecting radiation and the sources of radiation;
means for visually imaging the sources of radiation and their environment; and
means for moving the detecting means, distance determining means and imaging means through a range of altitudinal and azimuthal angles.

Abstract
A high-energy radiation survey system capable of imaging and determining the distances of, sources of incident radiation and of determining the energy of such radiation, incorporating a shaped radiation detector shield and detector configured therein for low-noise collimation of the radiation for directional mapping. The system is capable of being mounted on a remotely controllable vehicle and of being operated from an operator'"'"'s station remote from radiation hazards. The system can be used to generate high resolution radiation dose maps superimposed on a real-time video image of a room or other areas in nuclear power plants and other facilities using radioactive material.
