Spectroscopic Personal Radiation Detector

identiFINDER R200 is a rugged, pager-sized Spectroscopic Personal Radiation Detector (SPRD). The R200 provides full ANSI N42.32 Personal Radiation Detector (PRD) compliance and features next-generation solid state detector read-out technology that delivers ANSI N42.48 SPRD compliance with nuclide identification. The clear user interface and simple data presentation common to all identiFINDER products allow it to quickly integrate with existing operational protocols and reduce the training burden.

Radioisotope Identification

The ability to identify specific gamma sources enables front-line responders to perform immediate detection and response during a radiological event. FLIR's new SiPM technology in combination with Cesium Iodide (CsI) detector provides high-fidelity identification (≤7.5% resolution) so front-line officers can quickly determine whether a radiation source is a true threat or benign source from medical patients, normally occurring radiation, or industrial use. The identiFINDER R200 uses this next-generation solid state detector read-out technology to advance a radiological event from “alarm and wait” to “identify and take action.”

Pager-Sized and Rugged

At less than one pound, the identiFINDER R200 is lightweight and rugged enough to wear it on a belt without burdening the user. It is 1.5 meter drop-tested and IP67-rated so operators can wear it with confidence during routine traffic stops or high visibility events and in mass transit or critical infrastructure entry control points. It has a long-lasting internal rechargeable battery with additional external battery compartment for extended field situations. The identiFINDER R200 performs automatic calibration and stabilization and doesn’t require any user maintenance.

Shared Common User Interface

The identiFINDER R-series of products share a field-proven, common user interface and simple data presentation. With over 20,000 identiFINDER products deployed globally, the familiar interactions with the identiFINDER R200 allow it to quickly integrate with existing operational protocols while also reducing the training burden. Using the latest advancements in Bluetooth® and web server technologies, the OneTouch Reachback™ feature enables officers to send immediate notifications to other responders before arriving on-scene providing large-scale situational awareness.
