Gamma ray spectrometer MKSP-01 RADEK

Scintillation portable gamma ray spectrometer MKSP-01 RADEK is intended for measuring scintillation spectrums of radionuclides gamma radiation.

It is used for determination of activities and specific activities of radionuclides in samples and in conditions of natural occurrence in geometries 2p and 4p. The spectrometer can be used for operation in laboratory and also in field conditions ("in situ").

The basis of spectrometer is a monoblock in which a scintillator, a photoelectron multiplier (PMT), an  analog-to-digital-converter MD-208 (MCA - multichannel analyzer), a high-voltage and low-voltage modules are mounted. For fieldworks the spectrometer is placed in a thermoprotective housing, the cover of which is connected via a socket with the spectrometer.

Spectrometer contains a system of automatic stabilization of gain.
            It is produced with three types of detectors:
       BDEG-63 – on the base of monocrystal NaI(Tl) with dimensions 63х63mm;
       BDEG-80 – on the base of monocrystal NaI(Tl) with dimensions 80х80mm;
       BDEG-LB – on the base of monocrystal LaBr3.

Spectrometer technical information (in pdf):

    -         number of spectrum channels - 1024;
    -         maximum number of spectrums stored in the volatile memory – 200 (800);
    -         connection channel with PC – BlueTooth;
    -         channel capacity - 2³² countings;
    -         minimum operation time with accumulator – 10 hours.

A GPS receiver and a radio transmitting module BlueTooth are inbuilt in the spectrometer. Also the device contains a real-time clock, a volatile memory for settings and spectrums, a lamp indicator and a control button.

Spectrometer metrological characteristics:

Range of registered energies from 100 to 3000 keV.

Energy resolution with scintillation detection units BDEG-63 and BDEG-80 on line of gamma-radiation of  ¹³⁷Cs radionuclide with energy 661,7 keV doesn’t exceed respectively 9 and 9,5 %.

Detection efficiency of spectrometer in housing with detection unit BDEG-63 and BDEG-80 in full absorption peak with energy 661,66 keV of radionuclide ¹³⁷Cs of point source from the set OSGI, mounted closely to the end surface with energy 661,7 keV, is no less than 4 % and 8% respectively.

Maximum input statistical load of spectrometer is no less than 5∙10⁴ s^-1.

Time of spectrometer operation mode setting is no more than 5 min.

Time of spectrometer continuous operation is no less than 24 h.

Instability of spectrometer readings with detection units BDEG-63 and BDEG-80 per 24 hours of continuous operation is no more than 1,0 %.

Control:

The control of spectrometer by computer is carrying out by dint of universal program ASW.
By mobile phone or Tablet PC by dint of special program ASpectr (for OS Android, connection via BlueTooth) .
In field conditions the spectrometer can be controlled by dint of button (without PC or Tablet PC).

Pattern Approval Certificate of Measuring Instruments:  RU.C.38.001.A N42000.
