About Us
For five decades, Gammatron has manufactured and cared for sealed radioactive sources across their full lifecycle — from first design to final disposition.
A partner for the entire life of a source.
Gammatron is a Houston-based manufacturer of Am-241 and Am-241/Be sealed sources — and we handle what surrounds them: design, manufacturing, storage, logistics, leak testing, encapsulation, recycling, and disused source processing. It’s specialized, closely regulated work, and we’ve been doing it hands-on since 1973. The rest of the story is best told through the work itself.
