TSA BM285

Waste monitor with flexible options to screen medium-sized items for radioactive emissions.

High Sensitivity Waste Monitor for Medium—Sized Items
Efficient, Accurate Analysis
Touchscreen Operation
Cost Effective

The TSA BM285 is designed to screen medium-sized items for radioactive emissions and is ideal for monitoring prior to release from the facility. With an efficient and accurate go/no go analysis and typical scan times of one to three minutes, the BM285 waste monitor allows for cost effective waste management.

Advanced Design Features
The TSA BM285 high sensitivity and uniform measurement is achieved by using large volume plastic scintillator detectors on all six sides of the counting chamber for effective and accurate screening of all sides of the item. The load platform, containing the weight monitoring load cells, is mounted on sliding runners to facilitate easier loading of heavy samples. With lead shielding on all sides, the BM285 provides higher sensitivity and isolates the scanned item from any external radiation influence.

Programmable Detection Parameters
With the ability for an administrator to define screening parameters, customizing the TSA BM285 for specific radioactive isotopes or ‘waste streams’ is possible. The operator selects the proper waste stream from an annotated list for each item to be scanned, making the BM285 flexible when screening for multiple contaminants.

Easy-to-Operate
Operation is simple using the color touchscreen panel PC. Easy to read graphics provide instant reporting of system status and operating mode. Administrators can generate reports for all activity or only alarmed activity for efficient record keeping on waste disposal.

Flexible Options
With the optional scale the TSA BM285 is able to greater enhance facility operations. The BM285 comes standard with a stainless steel liner that protects the detectors and allows for easy cleaning if contaminated. An optional aluminum liner is available if greater sensitivity is required. With the optional sodium iodide detector, spectral isotopic identification to fit specific detection requirements is possible.
