BM-285E/BM-286E

TSA’s BM-285E bag monitor and BM-286E barrel monitor are trouble free instruments designed to measure gamma contamination of containerized material. The BM-285E can accommodate containers up to 500 lb., while the BM-286E is designed to hold 55 gallon drums weighing up to 1,000 lb.

An aluminum or stainless steel liner protects the detectors from the articles being monitored. The load platform, containing the weight monitoring load cells, is mounted on sliding runners to facilitate loading heavy samples.

Plastic scintillator detectors are mounted on all six sides of the counting chamber to provide uniform measurement throughout the chamber. The monitor’s high sensitivity is achieved by using large surface area plastic detectors coupled with microprocessor controlled electronics and sophisticated software algorithms.

User operation is made simple with the touch screen color monitor panel PC. Easy to read graphics provide instant reporting of system status and operating mode. Operator menus and error messages are clearly displayed. Ten different languages are currently available and are selectable from the panel PC. The user can change or modify any translated word or phrase to better convey the meaning.

From the keyboard, the system administrator can change all of the operation parameters. System operation and parameters are password protected with separate access levels. Report generation is automatic and continuous. Reports may be printed at any time.

Up to twenty different sets of operating parameters for different waste streams may be stored on disk. The operator selects the proper waste stream from an annotated list for each item to be scanned.

Applications

The BM-285E bag monitor and the BM-286E barrel monitor measure gamma contamination of containerized material.

The capacity of these units allow for monitoring large amounts of material in a minimum number of operations. The BM-285E can accommodate containers up to 500 lb., while the BM-286E is designed to hold 55 gallon drums weighing up to 1,000 lb.

Isotopic identification is possible with an optional sodium iodide detector, multichannel analyzer and applicable software.
