1) identiFINDER R300

The world’s first pager-sized spectroscopic personal radiation detector (SPRD) to offer full detection and identification capability in a single device. This product is the ideal solution for belt-worn passive scanning, security checkpoints, border patrol and first response.

2) identiFINDER R400

The best all-around handheld radiation detection and identification product you can find. With over 15,000 devices in the field, the identiFINDER R400 is the most trusted radio-isotope identification device (RIID) worldwide. This product is the ideal solution for all-purpose surveying, emergency response and environmental monitoring.

3) identiFINDER R500

The fastest and most sensitive radionuclide identification device (RID) for detection and identification of radiation sources. The identiFINDER R500 is as easy to use as it is powerful. This product is the ideal solution for truck and cargo checks, large area scanning and for locating and identifying shielded sources.

4) Stride™

The covert movement of special nuclear material or weapons into populated areas represents possibly the greatest threat to the security of our world. Radionuclide detection and identification systems are required to effectively detect or deter this threat by recognizing the presence or movement of radioactive material across borders, into government buildings, at large public gatherings and much more. The Stride system was designed for this purpose.
