Beta-Ray PM 10

• The Vasthi PM 10 and PM 2.5 Particulate Matter
  Monitors work The Principle of Particulate Matter
  10 Analyzer uses the following technology
  Ambient particulate matter, beta-ray detector for
  measuring the concentration of particulate matter
  whose aerodynamic equivalent diameter is smaller
  than 2.5/10 m on rolled filter tape The
  instrument uses low-radiation C14 as the
  radioactive source. The emitted ray passes
  through the filter membrane with contaminants and
  will be received by the detector. 91
