Aranet Radiation

A radiation detector measures ionizing radiation, the type of radiation that can displace electrons from atoms and potentially damage living tissue. Aranet Radiation measures two values: dose rate (µSv/h), which indicates the current level of radiation exposure per hour, and cumulative total dose, which tracks your accumulated exposure over time. Together, these give you both an immediate snapshot and a long-term exposure history.

Yes. Background radiation is present everywhere and comes from natural sources including soil, rock, cosmic rays, and trace radioactive elements in building materials and food. Typical background radiation levels range from 0.05 to 0.20 µSv/h depending on location, altitude, and local geology. A radiation detector helps you establish what is normal for your specific environment so you can recognize when levels change.

Aranet Radiation is calibrated for gamma (γ) radiation in a certified laboratory before shipping. The sensor is verified against reference radiation sources to ensure measurement accuracy. Calibration details and specifications are documented in the product datasheet available on this page. For context, laboratory calibration is the standard used by professional dosimetry instruments and is not typically performed on consumer-grade Geiger counters.

Dose rate (measured in µSv/h) tells you how much radiation you are receiving per hour at this moment. Total dose (measured in µSv or mSv) tells you how much radiation you have received in total over a period of time. Think of dose rate as your current speed and total dose as your total distance traveled. Aranet Radiation tracks both values simultaneously on its E-Ink display.

For general background monitoring, place the device in a frequently occupied room such as a living area or bedroom. If you suspect elevated radiation from building materials, soil, or stored items, place the detector near the suspected source. Avoid placing it directly on or against metal surfaces, which can affect readings. The device is portable, so you can move it between rooms to compare levels across different areas of your home.

Aranet Radiation runs on two standard AA batteries and is designed to operate for up to 4 years under typical conditions. The E-Ink display draws power only when refreshing, which significantly extends battery life compared to backlit LCD or OLED screens used in most Geiger counters. Batteries are included in the box.

No. Aranet Radiation operates independently without Wi-Fi or any network connection. It measures, calculates, and displays radiation levels on its own. The Aranet Home app connects via Bluetooth when you want to view historical data, export dose logs, or configure alarm thresholds. The detector functions fully without the app.

Aranet Radiation has a color-coded visual alarm (green, yellow, red) and an audible buzzer. Alarm thresholds are based on scientific exposure guidelines and can be customized through the Aranet Home app. Green indicates levels within the normal background range. Yellow indicates elevated levels that warrant attention. Red indicates levels that exceed the configured threshold. The audible alarm can be turned off if preferred.

Yes. The device is battery powered, weighs 220 g (7.8 oz), and does not require Wi-Fi or power cables. It is designed for both fixed home monitoring and portable use. A Navy Blue Travel Case is available as an accessory. This makes it useful for checking radiation levels in hotel rooms, rental properties, or unfamiliar locations.

Aranet Radiation is calibrated for gamma (γ) radiation, which is the most penetrating form of ionizing radiation and the primary concern for environmental background monitoring. Refer to the product datasheet for complete detection specifications. (Verify with Aranet: does the sensor also detect beta radiation? If yes, state both.)
