According to the Jerusalem Post a group of researchers from several universities including the Technion have a solution. “Based on previous studies showing a stronger likelihood of virus transmission indoors, the scientists suggest that fluorescent lamps, microcavity plasmas and LEDs inside ventilation systems can be effective at deactivating both airborne and surface-deposited strains of COVID-19.
On this basis, the team argues that investing a few billion dollars in such a technology in the form of UV-C sources can help protect billions of indoor workers worldwide.
Similarly, the deployment of UV light, according to the group, can lead to a return to routine activities such as working at the office, going to school and attending entertainment events. ”
UV-C is already being used by the Maayanei haYeshua hospital in Bnei Beraq. Obviously, this would be the solution for minyaniim of any size.
