Alpha/beta radiometer for low level activity measurements

Purpose:

• measurement of overall (total) activity of alpha-emitting radionuclides in "thick-shape" and "thin-shape" samples of environmental objects;
• measurement of total activity of beta-emitting radionuclides in samples of soil, water, on air filters and samples obtained by selective radiochemical extraction methods;
• measurement of alpha activity of nuclides in samples, which are obtained with radiochemical preparation, by radiometric method (using textbook of methodics);
• measurement of alpha activity of nuclides in samples, which are obtained with radiochemical preparation, by spectrometric method (using textbook of methodics and spectrometric kit “UMF-Spectrum”).

Features:

• simultaneous measurement of alpha and beta activity of the samples;
• use of silicon ion-implanted detector, area 500 mm² or 1000 mm²;
• active protection against background radiation with the use of gas discharge meters and anticoincidence circuit;
• passive sample protection against background radiation;
• mains protection against power supply interference;
• two-channel counter with timer to count pulses from registered alpha and beta particles;
• spectrometric signal output;
• communication with computer via USB/RS-232 interface;
• software "UMF-2000" for radiometer control, measurement results processing and report printing;
• determination of nuclides activity (after radiochemical preparation of sample):
  • in soil: Po-210, Sr-90;
  • in water: Po-210, Ra-226, Ra-228;
• calibration interval - 2 years.

SPECTROMETRIC KIT "UMF-SPECTRUM"

• designed to measure activities of alpha nuclides by spectrometric method;
• extra option for the UMF-2000 radiometer.
