It also applies to TRANSLUCENT PROTECTIVE PLATES used for protection against GAMMA RADIATION in nuclear medicine and BRACHYTHERAPY with automatically-controlled AFTERLOADING equipment.

It does not cover other translucent RADIATION PROTECTION materials, e.g.

− leaded glasses or goggles for protection of the OPERATOR'S eyes (eye spectacles),
