Introduction

The Model 4530 Series of Radiation Portal Monitors (RPMs) represents state-of-the-art technology for detecting low levels of radiation, such as orphan radiation sources and NORM (naturally occurring radioactive materials), at facilities including scrap yards, recycling companies, landfills, and foundries. These systems are composed of ruggedized, large plastic scintillation detectors optimally arranged to monitor items passing through. Each system can be configured with one to six large detectors, with individual detector volumes of 39.7 L (2117 in³) or 57 L (3500 in³).

Real-time data acquisition and analysis is performed directly at each detector system and then reported to the internal PC for logging, reporting, and alarm notification. Up to four detector systems (lanes) can be networked together via Ethernet or wirelessly to a central PC so that vehicles entering from either direction can be monitored in real time. An optional remote control/annunciator panel is available to support operator awareness, alarm acknowledgement, and if necessary, backup operation in the event the internal PC is unavailable.

Data from all the system sensors are acquired and checked by powerful, field-tested, and time-proven algorithms designed to check each load vigorously in a multi-dimensional and multi-layered manner before declaring any load as clean. Any abnormality is immediately indicated via both local and remote alarms. An optional camera system can capture an image of the offending vehicle and store the image with the logged data for permanent record keeping. Alarms can also be configured to automatically notify shift supervisors directly by e-mail if desired.

The system is designed for ease of use and can be customized to accommodate a wide variety of site and application specific criteria. Intuitive menus and controls combined with pre-defined automatic event handlers ensure each situation is handled properly and consistently.

All of the main components of these systems are manufactured in-house in the USA.

Retrofit Option

Ludlum Measurements offers the option to retrofit existing portal monitor systems with the electronics and software used in our Model 4530 Series Radiation Portal Monitors, including systems manufactured by our competitors. Retrofitting allows you to upgrade an aging system without having to purchase new detector housings and stands. Besides our own systems, Ludlum has experience retrofitting systems manufactured by Exploranium, RadComm, SAIC, Mirion/Canberra, and Thermo. Retrofits are customized to your needs, and can also include replacing the plastic scintillator detectors if necessary. Please contact us with your requirements.

Configurations

Ludlum offers several different RPM systems. Each 4530 Series model number suffix reflects the approximate total cubic inches of scintillation material used by the combined system.

Data Logging with Automatic Daily Back-Up

The base Model 4530 Series system includes vehicle monitoring software for the system control computer that can be used to monitor up to four separate Model 4530 Series configured systems (lanes) via an Ethernet or wireless connection. The software automatically collects and archives data from all available lanes, displays alarms, and generates reports. When equipped with optional cameras, the system can be configured to automatically capture images of vehicles passing through the system, either every vehicle or only those triggering an alarm, and store the images in the database.

The vehicle monitoring software has three main component programs:

Supervisor: Collects all data, saves to databases, and contains all parameter settings. It displays alarms and provides all control over the system.
Echo: Used for remote monitoring. It mirrors the Supervisor component and performs all alerting and reporting functions, but does not allow any control functions. Up to 10 Echo stations can be configured per Supervisor computer. Each Echo station can monitor an unlimited number of Supervisor computers.
Data Viewer: Used to query the databases (background, alarms, and event log), filtering records based on date, alarm, and lane number. The Data Viewer can also reprint an alarm report, print summary reports for user-defined data and time ranges, and create new databases based on the current search queries.

Reporting Feature

Ludlum’s reporting feature accumulates the data, and sends you an easy-to-read report on a regular basis (weekly, monthly, or quarterly) about the activity during that time frame.

Reports include:

How many vehicles passed through the system
How many radiation alarms occurred
Detail (date, time, extent) of radiation alarms
How many overspeed alarms occurred
Any other failure alerts or messages
Any unusual background radiation issues
Indication if vehicles are parking the system for too long
Indication if parameters have been changed

When you receive these reports on a regular basis, it’s easy to see when something changes, or when you need to address a training or hardware problem. You determine how often to get these reports, and you can also choose to have Ludlum technicians review the data for an additional fee.
