Ludlum Model 53 Portal Monitor (pre 2010 model)

The Model 53 Gamma Personnel Portal detects gamma radiation in or on personnel passing through the portal from either direction. This highly sensitive portal uses six large plastic scintillation detectors. Shielding is accomplished with either the standard 2.5 cm (1 in.)

Comes from a working lab in perfect working condition.

Smaller footprint than larger portal monitors at a cheaper entry point.
