High efficiency scintillation gamma detectors
Home / High efficiency scintillation gamma detectors
The company Ecophyspribor has developed and manufactured a set of high efficiency scintillation detectors of gamma-radiation. O the basis of these detectors it is appeared to solve traditional tasks of radioisotope technology in industry using radiation sources with activity at the level of natural radiation background or using only natural radiation background.
The typical arranging of a detection blocks (BD) is shown in the figure below. The real arrangement depends on the requirements to the device that comprised a detection block, namely:
-
variant of body arrangement depends on the operational conditions and on the dimensions of a scintillator NaJ(Tl),
-
the scintillator dimensions and electron circuit depend on the task that is solved by a device .
For solution of basic tasks 4 ground models of detection blocks are manufactured:
- BD-1 – universal detection block with built-in system of temperature and time auto stabilization;
- BD-2 – use only in level indicators in the solution with two detection blocks (annihilation coincidence circuit);
- BD-3 – universal detection block, simplified version of a device BPU-1K;
- BD-4 – made in a compact stainless steel body.
