Liquid scintillation spectrometer TRIEL
Technical and metrological characteristics
High-sensitivity spectrometer TRIEL based on a liquid scintillator is intended for analytical and technological monitoring of the activity of alpha and beta-emitting radionuclides (for example, H-3, C-14, P-32, Sr90+Y90, Pu-238, Pu-241, Pu-242, etc.). The spectrometer provides a complete radioisotope analysis of alpha, beta-emitting radionuclides (with the possibility of detecting beta radiation with energies from 2 keV, high detection efficiency (~ 100% for all alpha particles and for beta particles with energy> 50 keV).

Spectrometer - radiometer SKS-07P-B10 is a device for registering pulses arising from the interaction of beta or alpha particles with a liquid scintillator.
The count rate of recorded pulses is proportional to the activity of the measured sample, pulse amplitude is proportional to the energy of the particle that caused them.
On the basis of measurements carried out identification and calculation of activity of beta-emitting or alpha radionuclides in samples.
Spectrometer - radiometer SKS-07P-B10 consists of the detection unit with two photomultiplier, coincidence circuit, preamplifier, amplifier, multichannel analyzer and the microprocessor controller.
The signals from the both anodes of the photomultipliers are converted in the coincidence circuit and transmit to the input of the preamplifier, where it is amplified and specially formed for optimal signal / noise ratio and further it is converted into a digital code that is proportional to the absorbed energy.
The resulting data set is stored in the analyzers memory and forms the energy spectrum of the radiation - the dependence of the count of registered pulses of radiation energy.
The analytical software SpectraDec provides processing spectra and calculation activity of the radionuclides in samples.
