FAQ: T401 Non-IS – Radiation Contamination Monitor

What is a Radiation Contamination Monitor used for?

It is a handheld instrument used to detect and measure surface contamination (alpha, beta, gamma particles) on equipment, personnel, and surfaces in areas where radioactive materials are handled.

What does “Non-IS” imply?

Non-IS means it is Not Intrinsically Safe, and therefore, it cannot be used in hazardous (flammable/explosive) environments.
