Model SERIES VMF are high sensitivity Gamma Monitoring systems for determining possible radiation contamination

in containers or vehicles on a non-pause basis. plastic scintillation sheets have higher sensitivity than cylindrical

shaped scintillation crystals due to the larger surface area.

These systems can be installed at entrance and/or exit gates, at weight stations or check points, or anywhere that

cars, trucks, rail cars or pedestrians will pass by; preferably at reduced speeds for more accurate readings.

Background is continually updated and subtracted thus giving net vehicle reading.

• VMF-TA, VMF-TB, & the VMF-TA-4 includes the electronic control/alarm console plus two rugged weather

3 2

proof detectors each with plastic scintillation sheets with 792 involume each & a sensitive area of 528 in

each.

• The VMF-TA-4X & the VMF-TA-4X-O includes the electronic control/alarm console plus two rugged weather

area of 2210 ineach.

• Rate of change electronics with audio and visual alarms.

• Operates from 110/220 AC power main; optional battery back-up.

• Operation for rugged outdoor use as well as indoors with bi-lateral direction entry.

• Since the operation of this instrument is based on rate of change in radiation, it will reliably pick up contamination

as it passes near the monitor.

• Indoor/Outdoor Camera – Video capture of truck type, driver, and optional license plate capture.

• Free-standing strobe & horn alarm.
