Integrated Gamma Spectrometer
DESCRIPTION
Integrated gamma spectrometer is designed for registration of gamma quanta and measuring activity of radionuclides in solutions, water, food, vegetation, building materials, soil samples, radiopharmaceuticals, rocks, chemical industry materials, alloys, scrap metal and other technological products.
The device consists of a Ø51mm x 51mm NaI(Tl) crystal, a photomultiplier tube, a high voltage power supply unit, a preamplifier and a multi-channel analyzer within a common rugged housing. The whole system is entirely powered from the USB interface. Due to the integration of all hardware components required for a gamma spectroscopy system in one package, only one USB cable is required to connect the detector to a computer.

Gamma Spectrometer All-In-One based on NaI Detector
DESCRIPTION
Gamma Spectrometer combines NaI(TI) crystal of different sizes, a photomultiplier tube, a high voltage power supply, a preamplifier and a multi-channel analyzer module mounted within a rugged housing.
The whole system is entirely powered from the USB interface. Due to the integration of all hardware components required for a gamma spectroscopy system in one package, only one USB cable is required to connect the detector to a computer. This simplifies use and lowers the total costs of the gamma spectrometer.
The gamma spectrometer is operated with GammaPRO software package. The only requirement is that the host computer has an integrated USB high power hub or host port.
The Gamma spectrometer based on NaI detector is available with following detector dimensions:
- 51mm x 51mm (2″ x 2″)
- 63mm x 63mm (2.5″ x 2.5″)
- 76mm x 76mm (3″ x 3″)
Radiation Portal Monitors
DESCRIPTION
Radiation Portal Monitors (RPM) are permanently installed radiation detection systems designed for automated screening of pedestrians, vehicles and trains passing through the detection zone of RPM for presence of gamma and neutron radiation. The RPM alerts the security office and front line officer about the presence of radioactive and nuclear material and provides additional alarm associated information: type of alarm (gamma, neutron or both), relative amplitude of the alarm, etc.
RPM software functionality:
- Visual and audible indication of alarm
- Automated adjustment of the gamma-ray and neutron alarm thresholds without interfering with ongoing operation
- Provision of horizontal scanning profiles for neutrons and gamma radiation in case of alarm for each detector
- Interactive operator window with identified radionuclides list and corresponding count rates vs. time (semiconductor detector option)
- Documentation of the radiation alarm, including entering the results of secondary screening assessment
- Monitoring of the status of health of all subsystems (gamma and neutron detectors, occupancy and tamper sensors, on-pillar alarm indicators, temperature inside the housings, climate control, remote link and power supply)
- Recording, storing and processing of information
- Data retrieval from archive and review
- Log alarms
- Indication of count rate for individual detector in RPM
- Support LAN and TCP/IP connection
- Password protected setup of critical system parameters
- Automatic shut down and start up after loss of power
Liquid Scintillation Spectrometer TRIEL
DESCRIPTION
Hardware
Liquid Scintillation Spectrometer TRIEL is a device for registration of pulses arising from the interaction of alpha and beta particles with a liquid scintillator. The amplitude of the detected pulses is proportional to the energy of the particles that caused them, the pulse count rate is proportional to the activity of the measured counting sample.
The spectrometer consists of a light collection chamber with two PMT operating in the coincidence circuit and an electronic tract, including a high-voltage unit, a preamplifier, an amplifier, a multi-channel analyser, which measures the amplitudes of the pulse signals from the PMT and registers the received digital code in the buffer memory and further transfers information to the computer via USB or RS-485 interface.
The principle of operation of the spectrometer is based on the complete absorption of the energy of charged particles in a liquid scintillator, the emission of this energy in the form of a light flash, the conversion of the flash energy into an electrical pulse and the registration of these pulses using two PMTs. The analog signals from each PMT after amplification and formation go to the coincidence circuit for selection during the resolving time. The signal from the output of the coincidence system goes to the input of the MCA in which it is converted into a digital code proportional to the absorbed energy. The resulting codes are accumulated in the computer’s memory and form a spectrum of radiation energies.
The software allows you to control the operation of the spectrometer, process the spectra, and also identify radionuclides and calculate the activity in the counting samples. The processed results and spectra can be stored as files on computer storage devices or presented as reports.
To solve some radiochemical tasks of identifying and measuring the activity of radionuclides in samples it is possible to use measurement methods that should take into account the level of conformity of the counting and reference samples, the output coefficients during radiochemical concentration, and other relevant additional contributions to the error in determining the activities of radionuclides.
Software
The spectrometer is controlled by the “ASW3L” software, which provides control of the equipment using communication protocols, as well as display of the energy distribution (spectra), calculation and display of activity, saving and recording the results.
To solve the tasks of calculating activity in samples by decomposing complex spectra, as well as implementing analysis in accordance with additional measurement methods, the “SpectraDec” software is used.
