[ RadSafe ] Insulin Pumps and X-rays

Some electronic components are sensitive to high rates, and the instantaneous rate for a short pulse can be pretty high.   The accumulated dose may be low, but that's only part of the story.  I suspect that as parts shrink, and power decreases, that this susceptibility may increase.

Subject: [ RadSafe ] Insulin Pumps and X-rays

Multiple manufacturers of insulin pumps used by diabetics warn not to expose the pump to x-rays, including diagnostic x-rays and CTs. One manufacturer warns not to wear them during nuclear medicine exams. They warn to keep them out of the same room as an x-ray machine (even dental units), so this is not a warning about the impact on image quality. Does anyone understand how these devices could be so sensitive to small amounts of radiation? I was asked about this today by a radiology technologist, and I was unable to answer his question. I am skeptical that these pumps could be that sensitive and still function in the real world with fluctuating background radiation.
