TSA's BM-185E box waste monitor is designed to scan small items for radioactive contamination

The unit provides 4π geometry and efficiency of greater than 45% for 60Co.

The monitor's high sensitivity and uniform measurement is achieved by using large surface area plastic scintillator detectors on all sides of the counting chamber. The output from each detector is processed individually and sent to the panel PC by the system controller.

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. Ten different languages are currently available and are selectable from the panel PC. The user can change or modify any translated work or phrase to better convey the meaning.

The aluminium liner provides minimum attenuation. The BM-185E's electronics are mounted above the chamber which allows access for repair. The panel PC is mounted on an arm that allows for convenient access and retraction for protected relocation.

Beyond standard equipment the BM-185E offers user flexibility. For example the system can be equipped with an internal scale to permit specific activity measurements.


  • The BM-185E is designed to scan small items (less than 1 ft3) for radioactive contamination.

  • Ideal for monitoring small items prior to release and provides accurate go/no go analysis with typical scan times of just 1 to 3 minutes.
