Specifically, she used a combination of charcoal and petroleum as absorbents and an ionization vessel and showed that the presence of radon increased the electricity of the atmosphere. She found that the only factors that could cause changes were rainy periods of weather, which corresponded with lower emanation values. She published her findings in ''Chemical Abstracts''.
