Quick Start

Get started with Radiacode Zero in 5 minutes

Radiacode Zero is a portable wide-range radiation detector and dosimeter for real-time radiation assessment. The device measures gamma and X-ray dose rate, accumulates dose, automatically logs measurements, and warns of radiation hazards.

Step 1: Unpacking and charging

Unpack the device, check that it is intact and complete. Connect the USB Type-C cable to a charger (5 V, 0.5 A or more) or a computer USB port. Wait for a full charge — the blue indicator goes out.

Step 2: Turning on

Press and hold the round button (at least 3 seconds). The device starts in Monitor mode and begins estimating the dose rate.

Step 3: Reading the values

The screen shows the current dose rate estimate. While not enough data has been accumulated, the result is low-confidence and is shown with hatched digits.

Grid Item
  • Low-confidence values are shown with digits hatched with light diagonal stripes.
  • When the value is valid, the digits are fully filled in.
