Could airport security X-rays kill probiotics?

I cured my chronic yeast infection a year ago when I started taking acidophilus caplets. I took them on a trip in my carry-on luggage two weeks ago, and now the infection is back. Is it possible that the airport security X-rays killed the acidophilus? Meanwhile, I have started a new bottle.

No. It’s not at all likely. If low doses of X-rays were any good at killing bacteria, hospitals and labs would quickly abandon messy, cranky, dangerous, steam autoclaves, and replace them with neat little plug in radiation sources.
Bacteria are too tough to let a few high energy photons stop them.

I seem to recall a similar problem with acidophilus. The issue was not X-rays but rather heat. When I looked at the bottle closely it said to keep it in the fridge. :smack:
