Nuclear energy. Radiation protection. Individual thermoluminescence dosemeters for extremities and eyes. | Status: Withdrawn

1 Scope This International Standard provides performance criteria and tests for determining the performance of thermoluminescencedosemeters intended to be used for the measurement of radiation doses to the eyes and extremities (fingers, and limbs defined as hands, feet, forearms including the elbow, and leg including the patella), for photons from 15 keV to 3 MeV and beta radiation from 0,5 MeV to 3 MeV. It is conditional upon the use of an appropriate reader, procedures and ancillary equipment. It does not cover information access and data processing. This International Standard provides performance criteria and tests for dosemeters intended to measure dose equivalent at depths of 7 mg cm2 in tissue for fingers and limbs and 300 mg·cm2 in tissue for the eyes, including provision for the use of dosemeters only intended to be used once. Appropriate phantoms and dose conversion coefficients are recommended but others are not precluded. In all cases, performance is assessed under laboratory conditions which may not adequately simulate conditions actually experienced in personal dosimetry. For example, it may be necessary to sterilize dosemeters for medical applications. Therefore, caution is necessary in applying the results of these performance tests in real situations.
