Query: RNA Detection in air by means of Cosmic Rays interactions   The study research presented hereafter shows a new methodology to reveal
traces of Viral particles thanks to their own chemical structure such as P31,
an element making up part of the structure of RNA, a type of nucleic acid, such
as in a virus, in an open space or a closed ambient ( typically an airport
hall) detecting sub-atomic particles interactions with the air due to Cosmic
Rays , an Outer Space free source .This is constructed with the use of adequate
detectors (under development) looking in particular at the peculiar
interactions of muons, cosmic rays relativistic particle segment, with the no
living matter present as aerosol in the air.
