This part of IEC 61331 applies to translucent protective plates used for radiation protection in X-ray diagnosis and in X-ray therapy. 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),
-
— leaded face shields, which cover the entire face of the operator,
-
— patient eye protection, and
-
— thyroid/neck protective devices.
This Part 2 deals with the requirements on
-
— geometrical accuracy;
-
— optical quality of the material;
-
— spectral transmittance;
-
— radiation attenuation properties;
-
— marking;
-
— statement of compliance with this standard.
