Aptitudes of external irradiation measures devices destined to working zones survey or personal dosimetry to measure new operational quantities. Case of photons

Recommendations of ICRP advocating evaluation of efficient dose equivalent to estimate radiological risks, led ICRU to develop, to measure external irradiation, new operational quantities for practical use in radiation protection. After calling to mind of these quantities with their consequences on calibration of radiation protection measure equipment, is examined the aptitude to measure the new quantities of some radiation protection apparatus, particularly for working areas and for personal dosemeters destined to photons measures. 18 refs. 19 figs
