The nukeALERT 951 is the essential preventative radiological detection system to disclose the presence and intensity level of gamma radiation for nontechnical personnel. Its small, rugged, watertight and more sensitive than commonly used first responder radiation meters. Enhanced sensitivity is especially important when one is dealing with concealed radiological material, where the radiation levels may vary based on distance and shielding.

The nukeALERT 951 PRND system discreetly detects gamma radiation with either a vibration or audible alarm. The unit has a 2-year battery life and automatically recalibrates in high background environments. The belt clip and bright visual display promotes hands-free operation for the end user. The rugged micro-sized package provides a watertight, robust monitoring tool for HAZMAT and emergency response teams.

In the event of a radiological emergency, team members equipped with the nukeALERT 951 nuclear detection system can quickly and cost effectively monitor a large area because of a dramatic improvement in detector sensitivity and response time. Ease of use, sensitivity and operability under harsh environmental conditions make the nukeALERT 951 ideal for responders who work in emergency services, hazardous materials, and counter-terrorism.
