What does Aranet Radiation
measure?
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.
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.
