General Description

Imagine creating an instant, economical, roving web of radiation detection throughout your community using a miniature device that is carried effortlessly by each law enforcement professional and first responder on every patrol, event, traffic stop, 911 call, rail accident and overturned truck of unknown origin. Here is an opportunity to enhance your community's radiation detection capabilities infinitely.

This device, called K8, is already in use with CHiPs, Colorado and New Mexico State Police, and Las Vegas Fire and Rescue. Simple to understand and maintain, K8 will help detect, inform and mobilize your radiological experts faster, reducing harmful exposure.

Standing apart from the much slower, less sensitive Geiger-Muller (gas tube) key chain detectors, K8 uses solid state technology to immediately identify radiation presence, sensing and blinking at each radioactive particle and alarming both audibly and visibly in a few seconds at 5 mR/h. Each unit is tested by a physicist, CE approved, made in the USA, less than 1 ounce and hands free.
