don't get xrays

[Deleted member 16462]

No topic can be understood in isolation. People frequently ask me what they should do about their diagnosed osteoporosis/osteopenia, and when they mention “computer controlled” and “dual photon x-ray” bone density tests, my attention tends to jump past their bones, their diet, and their hormones, to the way they must perceive themselves and their place in the world. Are they aware that this is an x-ray that’s powerful enough to differentiate very opaque bones from less opaque bones? The soft tissues aren’t being studied, so they are allowed to be “overexposed” until they appear black on the film. If a thick area like the thigh or hip is to be measured, are they aware that the x-ray dose received at the surface where the radiation enters might be 20 times more intense than the radiation that reaches the film, and that the 90 or 95% of the missing energy has been absorbed by the person’s cells? If I limited my response to answering the question they thought they had asked me, I would feel that I had joined a conspiracy against them. My answer has to assume that they are really asking about their health, rather than about a particular medical diagnosis.

True but still get them if you need surgery or to check for cavaties, just not often. They are bad but sometimes the lesser of 2 evils etc.
