Rarely I think about it. But at times I wonder if we could have home gamma radiation machines to sterilise well about everything... From food to why not tooth brushes or other materials that don't handle heat or other options too well... Sadly gamma radiation generators will never be safe enough to be widespread for that. Still could it be workable?
