AlphaE is a versatile device for fast monitoring of Radon concentration in indoor & outdoor air. Being small & lightweight, it can also perfectly be used to measure personal radon exposure & to manage radiation dose. AlphaE is able to deliver precise & reliable measurement results after only 2 hours (faster response time with higher radon levels). Low radon levels below 100 Bq/m³ (2.7 pCi/l) can be measured as specified by the latest World Health Organization (WHO) recommendations (12% uncertainty at 1 sigma/24 hours).
