Beta ray area dosimeter

Gamma rayAlpha ray

Product introduction
Compact radiation monitor for dose rate and surface contamination measurements in clinical environments. Suitable for routine monitoring, area surveys and contamination checks in medical departments.

Technical Parameters
Detector: End-window G-M tube — Window diameter: ≥45 mm
Sensitivity: ≥5.8 cps at 0.01 μSv/h (Cs-137) — Measurement range: 0.01 μSv/h ~ 5 mSv/h
Surface emissivity α: ≥21% (Am-241, 2π sr); β: ≥16% (Cl-35, 2π sr)

Application Fields

• Department of Radiology: For routine area and equipment surveys, contamination checks after procedures, and verification of shielding and imaging rooms.
• Department of Radiation Oncology: For beamline and treatment-room surveys, patient contamination checks, and verification of local dose rates near therapy equipment.
• Department of Nuclear Medicine: For contamination monitoring in preparation and dispensing areas, uptake checks, and routine environmental surveys.
