The Radioactivity Data Logger is a small sensitive radiation meter used for monitoring X-rays, gamma and beta radiation. The Radioactivity Data Logger uses an energy compensated Geiger-Müller counting tube as detector for accurate measurement. According to the Radiation Protection Ordinance (StrSchV), it is mandatory in some areas to perform personal dosimetry using a Radioactivity Data Logger. The Radioactivity Data Logger is equipped with a powerful microprocessor and a TFT screen, which makes it easy to operate. 

The Radioactivity Data Logger itself has three alarm modes: sound, LED light and vibration. The alarm limit can be set as you like. When the alarm limit is reached, an alarm is issued, for protection. The main technical indicators of the device comply with the international standard.
