About SE International, Inc.
Since 1979, S.E. International, Inc. has been designing and manufacturing reliable radiation detection instruments under the Radiation Alert® brand. From our very first product—the Monitor 4—we’ve been committed to providing accurate, affordable tools that keep safety at the forefront.
Over the decades, we’ve built a reputation for honesty, innovation, and quality. Our diverse product line includes handheld survey meters, area monitors, multichannel analyzers, and portable laboratory systems used for detecting radiation in air, soil, food, and liquids. All of our Radiation Alert® instruments come with free software and updates to ensure long-term value and performance.
A Local Company with a Global Reach
We proudly partner with a global network of distributors to help customers find the right solutions for industrial, medical, educational, and personal applications.
Headquartered in Tennessee, we’re honored to have received statewide recognition for our international sales efforts and customer support. Yet, we’ve never lost sight of our roots. We actively support local non-profits and community initiatives through grants and donations, believing that strong communities build strong companies.

Clients Say
Gregory Field,

“We used SE monitors in Iraq and Afghanistan—sandstorms, snow, even camel licks couldn’t break them. Only mortar fire did. I’ve trusted them ever since.”
