DEPOSITION AND FILTERING OF RADON PROGENY DRIVEN BY ELECTROSPINNING

Electrospinnig is a process to create nanofibres by application of high voltage on the polymer solution. It is proved that nanofibres keep some amount of charge during their deposition and some of them are charged even few hours after that. The contribution discusses an interaction between electrospinning jet and ambient air containing Radon. Radon nuclear decay creates progenies which are mainly positively charged due to their beta decay and these positively charged Radon daughters are then attracted and trapped by negatively charged nanofibers. This process can be used in several applications to protect humans against charged radio isotopes like for example in the case of terrorist attack or as active filters of radon daughters. Several layers containing parallelized nanofibers have been prepared and preliminary tested as filters of ionized particles/nuclides.
