Just been for my regular dental check up and she took 2 x rays as I haven't had any dental ones for 5 years - should I have been offered a thyroid collar for protection or is this not normal procedure in the UK for standard dental x rays? Had dental x rays before and never been offered one but HA bad at the moment especially with relation to x rays and radiation and I made the mistake of googling about thyroid collars!! It was the type of machine that has an angled arm that is pointing directly at your cheek, on one side and then she moves it around to the other cheek - not the panoramic type that moves around your face. I was also sat up so I am presuming the angle and the type of machine means the beam does not cross the thyroid? Had a mammogram in November as well so am back panicking about too much radiation exposure!
