Abstract
Disclosed is a radiation monitoring system that has a radiation detector for making radiation measurements within a monitored area. An occupancy sensor may be provided for detecting a presence of an entity in the monitored area, and a motion sensor may be provided for detecting a motion of the entity in the monitored area. In a typical embodiment, a radiation measurement collection system is provided which has a first program logic element for collecting the radiation measurements as collected radiation measurements when the presence of the entity is detected and the motion of the entity is detected. Also provided is a method for monitoring an area for intermittent sources of radiation.
Claims14
A radiation monitoring system comprising:
- (a) a radiation detector for making radiation measurements within a monitored area;
- (b) an occupancy sensor for detecting a presence of an entity within the monitored area;
- (c) a motion sensor for detecting a motion of the entity within the monitored area;
- (d) a radiation measurement collection system comprising a first program logic element for collecting a first portion of the radiation measurements as collected radiation measurements when:
- (i) the presence of the entity is detected and (i) the motion of the entity is detected;
- and
- (e) an alarm system for activating an alarm signal if the collected radiation measurements exceed an alarm threshold value.
A method for detecting a source of radiation in a monitored area comprising:
