The NukAlert-ER™, with its unique 'Extended Range' Continuous Coverage from 1µR/hr through 600R/hr, performs all of the functions of the three devices that constituted our now lapsed Civil Defense Program. Plus, live reporting to your network!


It's a Geiger Counter suitable for evaluating personal and environmental decontamination and preliminary evaluation of food & water contamination.

·         It's a Survey Meter suitable for evaluating safe evacuation routes and safe sheltering options in a disaster or attack.

·         It's a Dosimeter for tracking cumulative exposure doses.

·         The NukAlert-ER™ is designed for First Responders, Civil Defense and individual personal and family protection.

·         EMS, Fire, Police, First Responders

·         Evacuation Routing Evaluations

·         Shelter Viability Evaluations

·         Hospital, School, Shelter Entrances

·         Food & Water Preliminary Evaluations

·         Decontamination & Remediation Tasks

·         Family and Individual Protection

·         Live on-line field reporting network

·         The NukAlert-ER™ can measure the higher radiation fields near a nuclear incident as well as any elevated levels still around months later or further away. 

·         The device can also be used to gauge the cumulative exposure dose of a single individual or group to aid wise decision making.

·         Intuitive and easy operation with user rate/dose alarm presets. Manual simplifies radiation level interpretation & proper action.

A Renowned Expert's Review of the NukAlert-ER

 "As documented in my recent book ACTIONS FOR SURVIVAL, First-Responders and the public alike can safely endure brief high levels of radiation exposure to save both themselves and others.  Unfortunately most available instruments are designed for low-level detection and are incapable of reading the much higher, truly life-threatening but manageable, radiation levels.  Without appropriate instruments First-Responders will be pulled back too far to do much good, and those in affected areas won't know if they have 10 hours or 10 minutes to evacuate safely.  NukAlert-ER is the first affordable 'Extended Range' instrument that provides seamless coverage, from uR/hr background measurement to life threatening levels up to 600R/hr. It is both an alarming rate meter and dosimeter with USB and optional Bluetooth for remote monitoring and reporting.  Throughout my over 60 year nuclear career, if I could have had only one instrument to assure my personal safety, the NukAlert-ER 'Extended Range' is exactly what I would have wanted. It will be a life-saver for both First-Responders and the public."
