RIID Recapitalization
June 20th, 2019
The US Department of Homeland Security has posted a Request for Information on RIID Next Generation: Radiation Detection Equipment and Operations
Are you considering responding to the Basic Handheld Program - RIID Recapitalization (Radseeker DLs)?
Saint-Gobain offers two solutions that will help you meet all requirements!
- CLLB for dual detection
- Enhanced LaBr for best resolution
What’s more? These are commercially available off-the-shelf! (COTS)
CLLB (95% enriched 6Li) is a gamma-neutron scintillation detector that is well suited for many different classes of hand-held instruments. Using Pulse Shape Discrimination electronics for Neutron Detection, customers can eliminate the need for an additional set of electronics and 3He detector. With dual gamma/neutron detection and an energy resolution of 4%, CLLB offers a dramatic change in what is possible in a hand-held instrument.
Saint-Gobain Crystals has been manufacturing CLLB detectors since 2017. Multiple customers have sampled this product, and there are several detectors currently in field-use.
With an FWHM measured at 2.2% at 662keV, Enhanced Lanthanum Bromide is the ultimate scintillator of energy resolution.
In addition, the 227AC peak of enhanced LaBr enables you to build a self-calibrating instrument, eliminating the need for external sources. The227AC peak, meanwhile, can be easily eliminated with pulse shape discrimination.
Saint-Gobain Crystals has been manufacturing Enhanced Lanthanum Bromide detectors since the fall of 2016. Multiple customers have sampled this product, and there are several detectors currently in field-use, both in the US & abroad.
Over its history, Saint-Gobain has deployed hundreds detectors in SPRDs, RIIDs, Backpacks, Mobile Systems and Portal Monitors across the world.
