AlphaE - Radon concentration monitor
AlphaE radon meter is a professional, electronic handheld device for fast and time-resolved radon monitoring in buildings, outdoors and in mines. Due to its ultra-lightweight design and sophisticated features, AlphaE is also highly suited to survey personal radon exposure and doses in workplaces.
The AlphaE’s favorable price-performance ratio makes it useful for service companies engaged in radon assessment and mitigation as well as for users in private homes. Can be used in nuclear industry, health, research centers, construction and recycling sites, etc..
AlphaE offers users the following features:
- Fast measurements
- Time-resolved measurement for exact radon determination
- This ultra-small and light-weight instrument comes with an optional belt bag, an alternative for wall-mounting
- Wide measuring range for professional use up to 10 MBq/m3
- Low radon levels below 100 Bq/m³ can also thus be measured as specified by the latest World Health Organization recommendations
- Battery operation up to 6 months of battery life; Permanent operations via mains supply are possible via USB port
- Cost-effective radon measurement for mitigation activities
Based on a silicon diode diffusion chamber, the sensitivity of the detector is 3 cpm at 100 Bq/m³. 80% of the final result is achieved after 2 hours (faster response for higher values). The calculation of the dose is performed based on user-settable factors for equilibrium and dose conversion.
