The FHZ 672 E-10 detector is a complex combination of organic scintillator material, a NaI(TI) crystal and extremely fast evaluation electronics. With this combination of detectors, an energy characteristic according to the ambient dose equivalent H*(10) is achieved. The high efficiency of this detector allows an accurate determination of the dose rate within a few seconds.
This combination of the famous blue NBR detector and the Multi Purpose Survey Meter FH 40 G portable system has unique features:
- The NBR technique (Natural Background Rejection) differentiates between natural radioactive material (NORM) and artificial, man-made sources
- Offers powerful detection of DU-materials (depleted uranium) in the field
- Tested and approved by TUV
- High gamma sensitivity: 2800 cps/µSv/h
- 1000 times more sensitive than normal gas filled detectors
- Measuring range of 1 nSv/h up to 100µSv/h and simultaneous measurement with FH 40 G up to 1Sv/h
- An artificial contribution of 10 nSv/h can be detected within a few seconds even in fluctuating background radiation fields in the range of 50 to 100 nSv/h
- Contaminated material or hidden sources are located fast and reliably
Flexible Data Storage
The stored measured values can be accessed any time and seen on the display of the advanced survey meter. For further processing and archiving purposes, it is possible to transfer the history contents to a PC via the FH 40 GL-10 interface.
Intelligent Ratemeter-Algorithm (ADF-Mode)
Guarantees that even the smallest changes of dose rate are immediately detected, while at the same time, statistical fluctuations are effectively suppressed.
Configuration by PC
The desired functions can be activated or hidden to the user by using the Windows*-based operating system. This means that the characteristics of the FH 40 GL-10 precisely correspond to the measurement task, thus operator errors are minimized. It can be made as simple or complex as required for user application.
