From a comment above “a chest X-ray is about 0.02 mSv where your annual dose from background is about 2.4mSv, but this easily can be twice this if you live at high altitude or in an area with a higher level of radioactive minerals”
So you get a choice between half the radiation from existing on Earth for a year, and a high tech diagnostic image, or… die from whatever disease you might have?
