Much has been written about increased public exposures to medical x-rays.  How about dental x-rays?  More & more dentists are using cone beam units for panoramic images.  In fact, a friend is asking me about doses from this procedure. He's concerned about dose to the thyroid and also to the lymph nodes in the neck.  He thinks the lead apron won't protect those lymph nodes.  Can someone shed some light on this?
