Dynasil Corp. [DYSL] has received a $2.5 million follow-on award from the Domestic Nuclear Detection Office (DNDO) to further develop and to provide samples of new, high performance nuclear radiation detector materials. Dynasil’s Radiation Monitoring Devices, Inc. subsidiary has developed scintillator crystals that are leading candidates to improve detection of radioactive materials. The scintillators convert radiation to visible light and are also lightweight, cover a broader range of detectable materials, and minimize false alarms, Dynasil says. The new funding is in addition to $5.6 million the company received last year from DNDO for similar efforts. “Homeland Security is very interested in our materials as new gamma and neutron technologies for threat detection,” says Kanai Shah, vice president of Research at Radiation Monitoring Devices.
