|
Gamma-spectrometer SEG-001p “AKP-S” is designed for determination of qualitative and quantitative composition of gamma-emission radionuclides in field and in laboratory conditions, search of radioactive sources and anomalies, gamma-survey of surface, gamma inspection of holes.
|
The spectrometer is designed for operation in wide range of temperatures, in vibration conditions, in conditions of raised humidity and dusting. The spectrometer can be used in rigid external conditions: by emergency, in situ, in mobile laboratories, in industrial and remote premises.

Lead shields are easily disassembled and transferred by one person, that lets measure samples as in the mobile laboratory, as develop a measuring post in temporary premises.
The spectrometer can be completed with:
- set of replaceable scintillation detectors Nal (TI) with crystals dimensions 40x40, 63x63, 100x50, 150x100 mm;
- submergence and hole detectors of different diameter and for different depths.
- tripod with adjustable height of detector installation above the surface of ground
- safety plastic case for detectors for work in field conditions.
The spectrometer allows:
- Carry out field measurements of gamma-emission radionuclides’ activity in ground for design of maps of pollution in wide range.
- Register changes of speed of account from detector for calculating of doze rate with step-type behavior up to 1 sec. during movement of the laboratory or the operator.
- Carry out measurements of specific activity in the samples and environments in laboratory conditions.
- Carry out search for radioactive sources and anomalies.
