Radiological Detection System

D-tect Systems Radiological Detection System (RDS) is a universal radiation detection system. The main feature is the Base Unit, which detects Beta and Gamma radiation, and acts as a common interface for six probes that are used for specialized radiation detection applications. ​

The Radiological Detection System was developed after the joint forces faced equipment interoperability challenges during Operation Tomodachi (the cleanup after the nuclear disaster in Fukushima, Japan).


  • One of the system’s defining features is its smart probe technology.

  • Any Rad Defender probe can be connected to any Base Unit without recalibration.

  • It stores over 45 hours of data that can be transferred easily to a computer for further analysis.

  • Rad Defender is ergonomically designed and can be used with protective gloves.

  • Its stealth mode and headphone functionality improves use when in combat situations.
