Aranet Radiation vs Aranet Radon Plus

The Aranet Radon Plus wins overall, with a higher owner rating, some weather resistance, a longer battery life and a wider sensor set covering radon, temperature, humidity and pressure. The Aranet Radiation only wins on price, and it measures an entirely different hazard.

What they measure. The Aranet Radon Plus is a radon detector that also tracks temperature, humidity and air pressure. The Aranet Radiation is a dosimeter for ionizing radiation, tracking dose rate and total dose, and it has no radon, temperature, humidity or pressure sensing at all.

Largely yes. Both connect over Bluetooth only, integrate with Home Assistant and no other smart-home platform, and use the same style of e-ink display, so the ownership experience is similar even though what each one reports is completely different.

The Aranet Radon Plus, which Aranet rates for noticeably longer than the Aranet Radiation on a set of two AA batteries, thanks to its low-power e-ink display and sensor design.

Choose it if radon is a concern in your home. It also brings a higher owner rating, some weather resistance and temperature, humidity and air pressure tracking alongside its radon sensing.

Choose it only if background ionizing radiation, not radon or general air quality, is what you want to monitor continuously. Its price is the one area where it comes out ahead of its Aranet sibling.
