Radon measuring device AlphaE - rental equipment
The Radon Meter AlphaE is a small, professional handheld instrument for continuous radon measurement. Thanks to its low weight and compact dimensions, the AlphaE radon meter is particularly suitable for determining personal exposure and personal dose.
Equipped with a diffusion chamber with silicon diode, the sensitivity is 3 cph at 100 Bq/ m³. With this, even low radon levels of 100 Bq/m³ can be measured (as required by the latest WHO recommendation: 12 % inaccuracy at 1 sigma/24 h). An equilibrium factor which can be set by the user allows the radon-induced dose to be estimated. The device was developed in cooperation with the Helmholtz Centre in Munich. Comprehensive measurements and user tests carried out by the Helmholtz Centre have confirmed the validity of the calibration and the error-free function even under extreme operating conditions (even at high humidity, e.g. in waterworks, mines, etc.).
The Radon Monitor AlphaE is battery operated and allows independent measurements with a battery life of up to 6 months. The Radon Monitor AlphaE can alternatively be supplied with mains voltage via the USB port. The collected measurement data are archived in the internal flash memory and can be read out via the USB port. Thus (with a 1-hour measurement cycle) the measurement data of a half-year can be stored. In addition to the radon measurement data, the signals of the integrated motion/manipulation detector and the temperature sensor are also recorded. The corresponding measurement times are also stored. A communication and readout software for exporting the data to Excel (or DataEXPERT) is commercially available.
