Banana equivalent dose - Wikipedia:
A banana equivalent dose is a concept occasionally used by nuclear proponents to place in scale the dangers of radiation by comparing exposures to the radiation generated by a common banana.
I was able to determine that a panoramic x-ray for your head is the equivalent of eating about 150 bananas:
0.009863 millirems per banana 15µSv / pan * 1 millirem / 10 µSv = 15 millirems / pan 15 millirems / pan * 1 banana / 0.0099 millirems = 150 bananas
I hope to break that one out to a patient… when I find the right combination of intellectual curiosity and concern for x-rays in a patient. That may, possibly, be never.
