Protective devices against diagnostic medical X-radiation - Part 2: Translucent protective plates

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.
