Enhancing Public Safety: How DHS and PSI Are Advancing Radiation Detection to Protect Large Public Gatherings and Events

The Department of Homeland Security (DHS) Small Business Innovation Research (SBIR) program plays a crucial role in fostering technological advancements that enhance national security. Through a competitive process, DHS SBIR issues topic calls and solicitations, inviting companies to submit proposals that address critical security challenges. Awardees are selected based on the strength of their proposals, their ability to meet stringent program requirements, and their potential to develop innovative solutions.

One such awardee, Physical Sciences, Inc. (PSI), based in Andover, Massachusetts, is leveraging SBIR funding to advance radiation detection technology, enhancing public safety in high-risk environments. Imagine celebrating New Year's Eve in Times Square, surrounded by millions of people, taxis, delivery trucks, and constant activity. In such a densely populated setting, security threats like radiological dispersion devices must be swiftly identified and mitigated.

PSI’s cutting-edge technology goes beyond simply detecting radiation; it enables rapid threat assessment and precise localization of the source, allowing authorities to take immediate action. Whether the threat comes from a backpack on a crowded sidewalk or a moving vehicle, this advanced detection capability is a game-changer for public safety. Through DHS SBIR’s support, PSI is helping to safeguard major public gatherings, ensuring that security professionals have the tools they need to protect communities from radiological threats.
