This dose rate probes 70 091 was developed to be able to provide efficient solutions to a great variety of measuring problems. Its field of application ranges from environmental monitoring to measuring functions in nuclear power stations. Two Geiger-Müller tubes are fully enclosed in a robust and waterproof aluminium housing. Counter tube combinations can be selected for optimum adjustment to the measuring problem to be solved. The digital interface RS 485 or USB (alternatively) makes it possible to communicate directly with a PC or build up networks with addressable single probes.
- high flexibility due to customized configurations
- wide measuring range
- robust and waterproof housing
- the probes are energy compensated according to IEC 60846
DEVELPEMENT OF NOVEL PROBES FOR THE MEASURING OF PHOTON DOSE RATES UP TO 100 SV/H
A dose rate probe consisting of two Halogen-quenched Geiger-Müller tubes has been designed for gamma radiation measurements at high-level radioactive samples. The detector provides dependable ambient dose-rate monitoring, covering nine dose-rate decades up to high values of 100 Sv/h. The dose-rate determination obtains serious benefit from a novel operation mode: The traditional counting is replaced by measuring the averaged time interval between the activation of the counter tube and the first detector strike. This approach is accomplished by a repetitive steering of the voltage up and down the operation point. The method is distinguished by an excellent linear detector response up to the highest dose-rates.
