Abstract
The behaviour of small radioactive ions resulting from a filtered and Radon or Thoron enriched air is studied. It is shown that these particles which initially have an electric load disappear and are replaced by electrically neutral particles, the size of which is studied to a base of time.DOI: 10.1111/j.2153-3490.1966.tb00274.x
