Clipart inspired by the real "Snow White" high volume air sampler produced by Senya, Finland and used by various organizations including IAEA and CTBTO. In fact it is like a big vacuum cleaner, but with air flow about 300 - 900 m³/h and captures small aerosol particles (including the radioactive ones) from the air to the filter. The filter is then exchanged and subsequently measured using gamma semiconductor spectrometry.
