The radioactivity data logger is a portable handheld device for the measurement of Beta, Gamma, and X-rays. A GM tube (Geiger-Müller counter) detects radiation exposure that can be harmful to humans and the environment. The real-time value, the average value, and the accumulated dose are displayed on the radioactivity data logger's large color screen. Additionally, the radiation dosimeter can display a bar graph of the most recent real-time measurements.

By setting an adjustable alarm threshold, the user can be alerted when the limit is exceeded. The radioactivity data logger has a data storage capacity for 167,857 values, which can be accessed with a simple button press.

The storage interval and automatic shutdown can be adjusted or disabled as needed. In the radioactivity data logger's settings, users can choose from 4 menu languages.

The radioactivity data logger is used in the general population, by individuals professionally exposed to radiation, and in other areas where there is a health risk associated with radiation.
