During COVID 19 pandemic, there is worldwide shortages of PPE, including N95 masks. So there is need to preserve the limited resources. So N95 masks are being reused. But there is no clear cut guidelines about the repeated use of N95. How many times you can use them? And is there a sterilisation technique for N95 mask after use ?

Hi
N95 masks can be reusable after sterilization ,i.e., in hot water, evey four hours, dependence on the usage of the masks.Also the filters of N95 masks can be disposable every four hours of usage

Answer
Hello All,
I agree that there is a danger in analogy, specifically, false equivalences. However, one can still see some similarities between radiation protection and SARS-COV-2 virus mitigation modalities. For example, droplets and aerosols exhibit short and longer range propagation behaviors, respectively, in a similar way to direct ionizing radiations (alpha and beta particles, short range due to Coulomb interactions with matter) and indirect ionizing radiations (gamma rays and neutrons, longer range due to no direct Coulomb interactions). In the case of radiative contamination, such as dispersed radioactive materials like plutonium contamination, the safety procedures are similar to the SARS-COV-2 virus procedures: full hazmat suits and washing down of these suits. And surprisingly, COVID-19 also has long term effects on the human body, which is also a hallmark of acute radiation exposure, even after the person is removed from the source of the exposure. Long-haulers, as some COVID-19 suffers are called, continue to exhibit unusual blood work and symptoms such as fatigue and headaches for weeks, months, and perhaps years after exposure to the SAR-COV-2 virus even if the titer of virus in their blood is too low to be detectable.
Of course, the real difference between radiation and the virus is that, hopefully, there is a vaccine against the virus.
Regards,
Tom Cuff
