  Radiation Alert® Sentry EC – Personal Alarming Dosimeter & Gamma Rate Meter
  Professional-grade personal radiation protection for executives, emergency managers, healthcare staff, and response teams.

The Radiation Alert® Sentry EC is a compact, high-reliability personal dosimeter and rate meter designed to safeguard personnel operating in environments with potential exposure to X-ray and gamma radiation. Purpose-built for operational accountability and real-time decision support, the Sentry EC provides continuous dose rate monitoring while permanently recording accumulated exposure — a critical requirement for compliance, post-incident reporting, and responder health protection.

Why a Personal Dosimeter Matters

Unlike simple alert-only radiation pagers, the Sentry EC records total accumulated gamma dose over time. This enables:

• Individual Exposure Accountability – Track cumulative dose for each responder, executive, or facility staff member during extended operations.

• Operational Rotation Management – Support personnel rotation decisions by preventing staff from exceeding exposure thresholds.

• Incident Reconstruction & Documentation – Generate exposure reports using free SentryCom software for after-action reviews, regulatory documentation, and liability mitigation.

• Health & Safety Protection – Maintain long-term exposure awareness during prolonged shelter-in-place operations or field response activities.

For organizations deploying Level-C PPE, shelter-in-place kits, or evacuation equipment, personal dosimetry is a foundational layer of radiological safety.

Integrated Alerting for Immediate Threat Awareness

The Sentry EC features customizable audible and vibrating alarms for both dose rate and accumulated dose thresholds. Users can select discreet vibration-only alerts for sensitive environments or audible click feedback for active field operations. A high-output 90 dB alarm ensures alerts are heard even in noisy operational settings.

Enterprise-Grade Data Logging & Software Support

With built-in internal memory and the included SentryCom software, the Sentry EC allows teams to download exposure data, generate incident timelines, and perform post-event analysis. This capability is essential for hospital emergency preparedness programs, corporate continuity planning, and municipal response documentation.

Ideal Companion for Radiation Alert® Detection Devices

The Sentry EC is the perfect partner to handheld radiation survey instruments such as the Radiation Alert® Ranger, Monitor 1000EC, Monitor 200, and Frisker contamination detectors. While survey meters locate radiation sources and contamination zones, the Sentry EC continuously protects the individual operator by tracking personal exposure in real time — creating a layered radiation safety system.
