Radiation Area Monitoring System

Radiation Area monitoring ensures that scientist, researchers and other users do not get contaminated while working on radioactive activities. There are many options for the users to choose from; the type of radioactive material detected, fixed/portable, the ruggedness of the instrument and the area of detection.
Ludlum provides basic radiation monitoring systems with different types of detectors that can be built on while SI Detection provides a more focus and in-depth solution for gamma detection. If you have other requirements, please contact us for more information.

Model 375 is Ludlum’s main system for radiation area monitoring. It can be mounted to a wall and it can be integrated with many different types of Ludlum’s detectors & accessories. These include remote indicator alarms, printers, relay outputs, weather-proof enclosures, Ethernet networking software, industrial cameras, and more. Other types of controllers for radiation area monitoring includes Model 3276. Model 3276 is mini handheld radiation area system that is a “plug and play” system, with internal and external radiation detectors. Click here to view the different configurations for Model 375.

SI Detection has different features; focusing on gamma detection, the ERFD is a more sophisticated radiation area monitoring solution. Its multi-purpose intelligent gamma detector not only is capable of continuous long hours monitoring but is also capable of transmitting information to designated users. The ERFD radiation area monitoring series can also be easily expanded by placing additional sensors. This model is designed specifically for radiation monitoring when the area is scattered.
