Reference # : Model No :

The Canberra Cronos®-4 Gamma Object/Tool Monitor is a high-performance radiation detection system designed to monitor and detect gamma radiation in various objects such as waste bags, tools, briefcases, hard hats, and other miscellaneous items. This monitor is ideal for ensuring that objects are free from detectable radioactivity, which can result in substantial cost savings in waste processing and storage. The Cronos-4 is equipped with advanced features such as fast-following background trending, a release-limit algorithm, and a low detection threshold, making it one of the most sensitive tools in its class. With its large counting chamber and six plastic scintillator detectors, the Cronos-4 delivers precise and reliable gamma photon counting. The device includes a user-friendly touch screen interface for easy operation and integrates with the Mirion WebRemote software for enhanced health physics and contamination tracking.

Benefits

The Cronos-4 Gamma Object/Tool Monitor offers several key benefits, including its extremely low detection threshold, high sensitivity, and efficient operation in varying radiation fields. The monitor’s large counting chamber volume (128.7 L) and thick lead shielding ensure optimal performance, making it suitable for meeting stringent user requirements. The user-friendly interface simplifies operation, and the integration with the Mirion WebRemote software streamlines the tracking and monitoring of contamination, improving health physics programs. Additionally, the device's robust and ergonomic design ensures ease of use and efficient decontamination. With features like built-in weighing scales and automatic/manual correction factors, the Cronos-4 ensures reliable and accurate results in radiation monitoring.

Limitations

Despite its advanced features, the Cronos-4 Gamma Object/Tool Monitor may have limitations in terms of portability due to its large size and weight, which may make transportation and setup more cumbersome in certain environments. The device is also highly sensitive, which may require careful handling to avoid false positives in high-radiation environments. Additionally, as a sophisticated piece of equipment, the Cronos-4 requires specialized training for proper use and maintenance to ensure accurate readings and optimal performance. Finally, the heavy lead shielding and size of the unit mean that freight shipping is required for transportation, adding to logistics complexity and cost.
