A Geiger-tube based, gamma radiation monitor developed to allow radiation dose measurements at a distance. The unit, which is stored in a wooden box (16 cm wide by 11 cm high by 76 cm long), has a 49 cm long probe and an 18 cm extender. Extension units available from the supplier, AUTOMESS (Automation und Messtechnik GmbH, Landenburg, Germany), allow the meter to work at a distance of up to 4 m from the radiation source. The instrument has a very wide dose-rate range of 0.1 mR/h to 1000 R/h (about 1 microsievert/h to 10 sieverts/h). It can be used to measure both total dose and dose rate. It was used by the CRNL Radiation Protection Branch at CRNL.
