Reply to comment by [deleted] in What are some of the mechanisms behind why long term physical inactivity and social isolation leads to chronic health diseases? by [deleted]
Sorry, I didn't make it clear in the title. What I meant was what particularly about the long term inactivity or isolation causes the increased risk of the conditions you mentioned. Is it because certain chronic inflammatory pathways are activated that causes actual tissue and cell damage because the immune system begins to target our own bodies? Some sort of immune system dysregulation?

Addendum: this is how radiation oncology works. Cancer cells are constantly dividing, healthy cells aren't, so cancer cells are killed more quickly.
That's the elevator pitch, anyways.

Keep in mind that the sample is tiny, the dose rate falls off as the distance squared, and only a small fraction of your body can be exposed to what ever the tiny Geiger counter right next to the sample tells you.
As far as bacteria etc goes they are far hardier when it comes to radiation, and to kill them takes billions times more radiation than your sample emits in an hour.

OP was talking about freeze thaw. The expanding of the ice would be the problem.
