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.

Abstract: A system and method for detection of alpha particles generated by a test material in proximity to a light atomic weight element. The system includes a neutron detector that is configured to detect a rate of generation of neutrons produced by an (alpha, n) reaction between the test material and the light atomic weight element. There is also at least one gamma-ray detector configured to measure a rate of generation of 511 keV gamma rays produced by an annihilation reaction triggered by a positron emission from a daughter product of the light atomic weight element. A comparator is configured to compare the rate of generation of neutrons and the rate of generation of 511 keV gamma rays.

Abstract: A rules-based printing device component management system and methods for use are described that allow a printing device component vendor to monitor printer component conditions in multiple organizations. The printer component conditions are compared with one or more rules defined for the printer and its components to determine if a printer component requires replacement. The rules may be defined by the organization or the vendor and may be stored at a vendor site to efficiently manage replacement of depleted or broken printer components.
