The new ones that see under your clothes? Some scientists are now saying that they think the equivalent amount of radiation may not be calculated correctly and they are not certain how much radiation the machine is pumping out.
I wasn't planning on using them and now I'm definitely not. I already have one mutation causing my immune disorder, I don't need to stack more on top of it.
http://www.npr.org/templates/story/story.php?storyId=126833083 Here's another interesting story on Googleitis, people diagnosing themselves (usually wrong) using the internet. I find it amusing, but it also strikes a deep note in me as that's how we diagnosed my condition. We went to two specialists. One said no, I had not had pneumonia, that it was all caused by asthma (103f temperature? I don't think so.) My immunologist was initially chasing an allergies line, saying that CVID in a person my age was extremely rare. Guess what? 10% of the population of CVID people are diagnosed in my age decade. Not exactly rare. If we had not pushed for an IgG test, there's no telling how much longer I'd be waiting for an accurate diagnosis and treatment.
