Introduction

 

Automating routine contamination frisking using instruments like Ludlum's Small Article Radiation Monitor is a well proven methodology for ensuring items leaving controlled areas are clean.  Ludlum's new Model 54 has adopted time-tested and proven concepts gathered from throughout the industry and integrated it into a new ground-up design that employs the latest computer and detector technologies.  The result is a more robust, user-friendly and cost-effective design than those currently available.
 
Ludlum Model 54 Small Article MonitorCentral to the design is the detector chamber which is configured to deliver the largest and most sensitive detection volume presently available for this type of monitor.  The specially designed large area, 2" thick plastic scintillator radiation detectors are arranged to optimize the sensitivity throughout the chamber.  A stainless steel liner protects the detectors while facilitating decon. The chamber can be configured with either 4 or 6 radiation detectors and either 1" or 2" of lead.  The lead is shipped separately and easily loaded on site.
 
Ludlum Model 54 Small Article MonitorThe Model 54 comes equipped with two doors which can be mounted with either a left or right-hand swing.  This is accomplished using hardened steel door hinges  which are securely bolted to the instrument frame and employ ball-bearings that make operating the doors as easy as possible.  Solenoid activated door locks may be configured by the user to support logistics for single or pass-through type operation.
 
Ludlum's new QPASS algorithms provide a means whereby administrators can optimize the settings best suited for their operations.  QPASS additionally surpasses all other technologies via built-in intelligence that can automatically optimize settings as the count begins to deliver the most efficient and effective count possible.  It's a perfect balance between minimum count time and maximum sensitivity that affords eliminating a second count to verify any alarms.
 
Operational status and instrument condition is clearly presented to the operator via a large 12" touch screen LCD.  A second LCD mounted to the opposite side is optionally available where desired as in the case of pass-through type operations.  The screens are designed to be very intuitive and are accompanied by a large size push button to activate sample counting and two smaller push buttons for updating the background or acknowledging any alarms.  The main counting screen is locked with password control access via the touch screen to either routine check functions at one level or a second level accessing all parameters.
 
The electronics support the latest Ludlum detector boards which are connected to a PC-based fan-less controller motherboard running on Embedded WindowsTM XP platform.  The system also provides an Ethernet port that enables connection to the site LAN for collecting all count and alarm data as well as monitoring all activities remotely from one or more locations.
 
When taken in total, Ludlum's Model 54 Small Article Radiation Monitor delivers state-of-the art technology in a robust design with enhanced performance, user-friendliness, and connectivity at the lowest cost on the market.
