MKC-03СА – a professional small personal dosimeter-radiometer with a little time measurements at the level of natural background radiation and the speech  measuring results, intended for:

  • measurement of the ambient dose equivalent of gamma – (x-ray) radiation;
  • measurement of ambient equivalent dose  rate of gamma – (x-rays) radiation;
  • measurement of beta – particles flux density from contaminated surfaces;
  • measurement of specific activity of radio nuclides in samples of food products and other objects of environment;
  • evaluation of alpha- particles flux density;
  • evaluation of ionizing particles flux in the mode «SEARCH»;
  • on-site search for sources of ionizing radiation, control of radioactive contamination of banknotes and their packages and operational assessment of the radiation situation

(The program is a programming model that runs on a PC (OS Windows), and behaves almost identically to the real device)

Distinctive features

  • fast change of the testimony in statistically significant change of the intensity of the radiation;
  • built-in end gas-discharge counter of gamma-, beta-  and alpha- radiation with the total area of the input window of the detector 39 cm2 with a removable filter compensates for with a sensitivity to gamma radiation 45 000 imp/mSv,  the effectiveness of the registration by beta radiation 90Sr +90Y – not less than 65%, the alpha – radiation of 239Pu – not less than 20%;
  • voice reproduction of the results of measurements of dose rate of gamma-  radiation and their voice assessment («OK»,«WARNING»,«DANGEROUS») in Russian or English;
  • sound (clicks) and visual alarm radiation intensity;
  • large graphic LCD with backlight;
  • simultaneous display the results of the measurement in the digital and analog form, units of measurement, current statistical error of measurement, a set threshold alarm measured value (which determines the maximum value of the analog scale), the sequence number of the current record in the journal of measurements, time, date and day of the week;
  • tone sound signaling when exceeding a user-defined threshold dose, flux density of beta – and alpha – particles and the flow of ionizing particles;
  • recurring or hand write in the journal of measurements with non-volatile memory of up to 2000 results of measurements of the dose, the dose or flux density of ionizing particles with their current statistical error, the date and the time of their conducting;
  • possibility of data exchange with a PC (via USB port).
