Assignee:

Saint-Gobain Ceramics & Plastics, Inc. - Worcester MA

International Classification:

G01T 1/10

Appl. No.:

12/650260

Inventors:

Artan Duraj - Seven Hills OH, US

Assignee:

Saint-Gobain Ceramics & Plastics, Inc. - Worcester MA

International Classification:

G01V 5/00

US Classification:

250262

Abstract:

A detector includes a sonde having a housing and comprising a scintillator disposed within the housing and a calibration source coupled to the scintillator to fluoresce the scintillator at a known wavelength of electromagnetic radiation. The detector further includes an electromagnetic radiation sensing device coupled to the scintillator and disposed within the housing and a first programmable/re-programmable processing module (PRPM) coupled to the electromagnetic radiation sensing device and disposed within the housing. The PRPM is programmed to process signals from the electromagnetic sensing device based on a user-defined analysis mode selected from the group of modes consisting of filtering, windowing, discriminating, and counting.

International Classification:

G01T 1/20

US Classification:

250369

Abstract:

A radiation detection system can include a scintillator that is capable of emitting scintillating light in response to capturing different types of targeted radiation, a photosensor optically coupled to the scintillator, and a control module electrically coupled to the photosensor. The control module can be configured to analyze state information of the radiation detection system, and select a first technique to determine which type of targeted radiation is captured by the scintillator, wherein the first technique is a particular technique of a plurality of techniques to determine which type of targeted radiation was captured by the scintillator, and the selection is based at least in part on the analysis. In an embodiment, the radiation detection system can be used to change from one technique to another in real time or near real time to allow the radiation detection system to respond to changing conditions.
