Even more interesting than other sources is the fact that many spinal and similar surgeons reach their lifetime radiation exposure limit in just 10 years of practice. Many (most?) end up with cataracts or other tell tale symptoms of radiation exposure. It's because of all the x-rays needed for minimally invasive surgury.
I apologize for not posting it in the first place.
