Radiation Alert Ranger® EXP
Professional Portable Radiation Survey Meter for Field and Facility Operations

The Radiation Alert Ranger® EXP delivers laboratory-grade sensitivity in a rugged, portable platform designed for real-world emergency response, industrial safety, environmental monitoring, and regulatory compliance. Available through LevelCPPE.com, the Ranger EXP is a core radiation survey instrument for organizations that require fast, accurate detection of alpha, beta, gamma, and X-ray radiation across a wide range of operational environments.

Compact and lightweight, the Ranger EXP is engineered for high-sensitivity detection of NORM (Naturally Occurring Radioactive Material) and low-level contamination while maintaining the performance standards required for professional survey work. Built-in isotope efficiencies allow the instrument to calculate activity directly in Becquerels (Bq) and Disintegrations Per Minute (DPM), enabling rapid contamination assessment without external conversion tools.

The intuitive user interface features a backlit graphic display, red count indicator light, and audible beeper that signals each radiation event for immediate situational awareness. Adjustable alarm thresholds, selectable alert modes, and programmable timers allow emergency managers and safety officers to configure the instrument to match mission-specific response thresholds and regulatory limits.

Integrated Data Management and Mobile Connectivity

The Ranger EXP includes free Observer USB Software for Windows, allowing users to download survey data, configure alarms, generate reports, and archive readings for compliance documentation and after-action review.

With the optional Bluetooth module, the Ranger EXP wirelessly connects to the Radiation Alert® Observer BLE mobile app for Android devices. This enables real-time remote viewing of radiation levels, GPS-tagged survey logging, timed counts, data sharing, and mirrored alarm notifications directly on mobile devices, improving field coordination and situational awareness during multi-team operations.
