Vehicle-based radiation monitoring for mobile surveys

Mobile radiation surveillance lives or dies on situational awareness. A survey vehicle typically carries several detectors — gamma and neutron, mounted on the body and inside the cabin — each producing its own pulse stream. Without a single point of aggregation, the crew is left glancing across separate readouts while the vehicle is moving, and nothing ties the channels together into one picture of the radiological situation around the vehicle.

The team needed every detector signal on one platform: per-channel rates at a glance, programmable integration to match survey speed, alarms that do not require watching the screen, and a log that supports post-survey review — all running from the vehicle's own DC supply, with no inverter and no rack of separate instruments.

The Eight Channel Count Reader System accepts up to eight detectors on one platform — pulse and TTL inputs, gamma and neutron compatible — and meters each channel independently. Integration time is programmable per survey profile, so the crew can trade response speed against statistical smoothness depending on whether they are creeping a perimeter or driving a transect.

Audio and visual alarms fire per channel, so a threshold crossing announces itself while the operator's eyes are on the road. Every reading is logged on board, giving the team a defensible record for post-survey review and reporting. The whole system runs from the vehicle's DC input and presents everything on one centralized in-cabin display.

One platform, every detector

Because the channel front-end is detector-agnostic, the same reader serves emergency-response fits, perimeter checks and environmental survey configurations — the detector mix changes, the cabin workflow does not.
