  • Page 11 In the mode «SEARCH» the calculation of particles detected with the gamma- detector and the beta-detector is carried out and the total number of impulses, calculated during the measurement period appears on the display. The «SEARCH» profile allows you to locate the source of radiation according to the change of the detected particles fre- quency and the indications on the display.
  • Page 12 B) In the mode «MEASURE» taking the background into account the dose rate and flux density evaluation is executed. But the display for each type of radiation output at the same time shows two indications: for gamma radiation - the dose excess above the background dose rate and the background dose rate value for beta-radiation –...
