Overview

The BG9611 intelligent alpha and beta surface contamination detector is suitable for detecting low-level alpha and beta radiation surface contamination. The instrument adopts a dual flash detector with high detection efficiency; The same probe can simultaneously measure alpha and beta particles and automatically distinguish between them, making it an ideal instrument for detecting alpha and beta radiation surface contamination in fields such as environmental laboratories, nuclear medicine, molecular biology, radiochemistry, nuclear material transportation, storage, and inspection. This instrument adopts single-chip control, which can achieve continuous data acquisition, storage, and can be queried at any time.
