IEC 61331-2:2014 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; and – statement of compliance with this standard. This second edition cancels and replaces the first edition of IEC 61331-2, published in 1994. It constitutes a technical revision. This second edition has been adapted to apply to the present technology. The essential changes and extensions are: – extension of scope to cover all kinds of translucent protective plates and all kinds of radiation qualities and gamma radiation; – removal of definition and requirements for translucent protective plates for visual imaging; – changes of requirements concerning geometrical accuracy and optical quality; – changes of requirements concerning determination of lead equivalent and minimal thickness; and – changes of requirements concerning information and marking.
