What does Aranet Radiation measure?

Dose rate

describes how strong the ionizing radiation (γ, β) is at a given moment. It is expressed in microsieverts per hour (µSv/h) or millirems per hour (mrem/h).
If radiation levels rise, the device uses colors (green, yellow, and red) to alert you, dimming the screen for high values (red level). The default threshold levels are based on scientific recommendations 1-4 , but you can adjust them as needed through Aranet Home app.

Total dose

of ionizing radiation (γ, β) encountered during the integration time is expressed in millisieverts (mSv) or rems (rem). Total dose of ionizing radiation is a critical metric for ensuring environmental safety and personal health. If the average rate at which the total dose has been acquired exceeds 0.20 μSv/h, then the upper part of the screen will be dimmed.
This reading can be reset from the Aranet Home app or by pushing the mechanical button behind the battery compartment lid marked “Cal”. To perform a reset, press and hold the button for 5 seconds.

When a reset is performed, the data will be permanently lost. You should reset this history only if:

The device is passed to you by someone else and the data does not apply to you anymore.
You just want to start fresh, like at the beginning of a new year, as the data will be permanently lost.

Setting up the device

Insert the batteries, and your Aranet Radiation device is ready to go! Please wait a few minutes for the first measurement to appear. When the dose rate numbers change from outlined to filled, you can begin your measurement journey.

CAUTION

Do not remove the sticker on the back of Aranet Radiation
Aranet Radiation is not impact-resistant. Exposure to strong accelerations can lead to erroneous device
Do not expose Aranet Radiation to high-humidity
Exposing the sensor to X-ray scans, like those at airport baggage controls, temporarily raises the dose rate reading and total dose readings, which can be disregarded or mitigated by removing the sensor batteries during scans.

Configuration switches

Switches can be found behind the batteries. Use the attached pin to adjust these settings.
