Leak Testing
Professional leak testing for radioactive sealed sources, worldwide — a straightforward program that keeps you audit-ready, from kit delivery and sample analysis to fast reporting and long-term compliance support.
Sealed source leak tests & swipe surveys.
When it comes to radiation safety, regular testing is critical — both to meet regulatory requirements and to protect your team and environment. Two of the most common methods for detecting potential contamination are sealed source leak tests and swipe, or “wipe,” surveys.
A sealed source leak test verifies that a radioactive source is not leaking radioactive material — confirming your source stays compliant, safe, and ready to use.
