Standardi ajalugu

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.
