Introduction

The Ludlum Model 4906A is a low cost, industrial duty, alpha only radiation contamination monitoring system for checking personnel hands and feet. A large color LCD presents users with the system status and points out any potential contamination. The system employs six air proportional type detectors with counting activated by optical switches. Alarms are annunciated locally and can be augmented with optional relays and or a light stack. The built-in Ethernet interface supports connection to a network for gathering all count cycles and remote monitoring of the status. All maintenance can be performed from the front of the instrument. Detector access for quick replacement or repair is facilitated by hinged top covers.
