Thanks for the update & I agree. I suspect your sister was not even told to stay away from children or pregnant women for 24 hours after her release. Many if not all of the hospitals actually have the patient take the radiation and then sit out with other patients & families in the waiting room while the doctors wait for the radiation to pass fully through the patients body for the exam. While in the waiting room this patient and other patients or visitors in the waiting room are unknowingly receiving high doses of radiation. A newly pregnant mother with a small fetus sitting next to a patient such as your sister might even have a miscarriage as a result or many other problems as a result. I believe nuclear medical testing is mishandled just as nuclear waste has, very poorly and misunderstood.Sorry to hear your sister is having medical issues that required this type of testing, I suspect a stress test.
