PURPOSE
Fast, reliable, analysis of solid and liquid radioactive waste (RAW) located
in barrels of 200 dm3
APPLICATION
- Control of (RAW) at its generation and processing facilities
- RAW control at storage facilities
- The quality control and inventory monitoring of the production at nuclear
processing facilities
FEATURES
- Parallel recording of gamma-spectra at three levels along the height of
the barrel
- Automatic rotation of the barrel around its axis during the measurement
- Use of attenuation filters during measurement of high-level waste
- Determination of the composition of gamma-emitting radionuclides and their
specific activity
- Automatic classification of RAW into categories according to specific activity
- Control of gamma radiation dose rate
- Storing of measurement results and spectra in the data base with possible
authorized access through the local network
- Generation of a report on measurement results in accordance with the operator's
request
- Two optional designs: with a built-in computer and with possible connection
of a remote computer
COMPONENTS
- Three spectrometric collimated gamma channels on the basis of the NaJ (TI)
crystal
- Gamma dose rate sensor
- Industrial computer
- Software
- Weighing device
- Controllable rotating platform
