The Radiation Detector is a small sensitive radiation meter used for monitoring X-rays, gamma and beta radiation. The Radiation Detector 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 Geiger counter. The Geiger counter is equipped with a powerful microprocessor and a TFT screen, which makes it easy to operate.
