Countroom

Countroom focuses on high-precision fission product measurements and alpha spectrometry

The Countroom Team occupies a 7,000 square-foot facility with manual and automated gamma spectrometers, alpha spectrometers, beta counters, liquid scintillation counters and autoradiography scanners. Many of these systems date back to the beginning of nuclear testing. We also maintain historic calibrations of these systems.

This team is capable of quantifying activity from sub-environmental and bioassay levels to highly radioactive, freshly irradiated materials. The team supports many institutional programs, as well as treaty monitoring efforts at national and international levels.

Equipment in our facility

• More than 80 gamma spectrometers
• More than 100 alpha spectrometers
• Two liquid scintillation counters
• Six beta counters
• A high-purity germanium Clover detector
• Digital autoradiography
