It’s the invisible elephant in radiology — radiation exposure. As physicians, we know all too well that exposure to radiation should be limited to the least amount possible. We have all learned about the ALARA principle for keeping exposure low. We also take precautions on our patients’ behalf and educate them. But what about us? The physicians and technical staff who treat patients every day cannot avoid radiation exposure entirely. However, there is growing evidence that not only is radiation exposure detrimental to our health, but also many long-term cumulative effects are still unknown.
