Alpha and beta particle detectors currently employed in field operations suffer from frequent damage to the aluminized mylar window on the face of the detector. To address this deficiency, Corvid Technologies, LLC proposes a new type of alpha and beta particle detector that replaces the aluminized mylar window with a permanent titanium coating, which has been shown to allow alpha and beta particle ...

In Phase I, we propose next generation of windowless radiation detectors which will be low power for long field use, compact, extremely rugged, cost effective, easy to use, and reliable. Field-portable radiation detectors are a widely used technology for defense, environmental monitoring, and industry applications dealing with radioactive sources. From nuclear weapon accident emergencies to routin ...

The objective of this proposal is to develop enabling technology for the production of bulk scintillating nanocomposites that have gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings. These ‘ultra-composites’ w ...

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...

STANDARD MONTE CARLO AND FN METHODS FOR RADIATION TRANSPORT WILL BE USED TO STUDY A NEWLY PROPOSED SHIELD CONFIGURATION FOR PROTECTION AGAINST PARALLEL OR SLIGHTLY DIVERING GAMA RAY BEAMS IN A SPACE (NON-SCATTTERING) ENVIRONMENT. THE NEW CONFIGURATION EMPLOYS LAYERED SHIELDS, WITH CONSIDERABLE SEPARATION BETWEEN THE LAYERS, TO SHADOW THE TARGET, OF THE ASSUMPTION THAT THE DIRECTION OF INCIDENCE IS ...
