Doctor Invents 'Zero Gravity' Radiation Suit

Posted by samzenpus on from the baron-harkonnen-approved dept.

DrFrasierCrane writes "You think you feel weighed down when your dentist lays that lead apron on you to take X-rays: how about the doctors who deal with radiation treatments and have to wear those aprons all day long? A Dallas, Texas, doctor has created a 'zero gravity' radiation suit for just that problem. From the article: 'Physicians are supposed to wear a lead apron during those procedures. It is back-breakingly heavy and doesn't cover the body completely. The zero gravity suit eliminates the weight and the exposed openings.'"
