Geiger Counter Radiation Detector Portable Xray Gamma Beta Marble Radioactivity

Meet the portable Geiger Counter Radiation Detector, a compact instrument that reads β, γ, and X-ray exposure with Real-Time, Average Value, and Cumulative Value measurement modes for quick, reliable screening on the go.

Its energy-compensated GM tube (48x6.5 mm) delivers precise readings in a compact 165 × 14 × 12 mm body, weighing about 44 g. The device supports dose units in μSv/h and mSv/h and provides a clear high-definition display for easy visibility in any setting. Battery power requires 2× AAA cells (not included).

All electronic and mechanical equipment sold by InterCyprus to EU countries is CE certified and carries a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability.

Benefits & Tips

• Quick on-site screening of ambient radiation or material samples (β, γ, X-ray) without specialized gear.
• Three measurement modes help you decide: Real-Time for immediate danger, Average for stable readings, and Cumulative for exposure tracking over time.
• Ideal for checking marble or other building materials for radioactivity during renovations or inspections.
