| | |   Thyroid shield. This is a lead-impregnated cloth shield, designed to be worn around the neck to protect the radiation-sensitive thyroid gland from damage when x-rays need to be taken of this general area of the body, but the thyroid itself doesn't need to be visible.
 It's quite heavy, because inside is a layer containing a high percentage of lead in some sort of resin material (my percentage below is just a guess).
