| Abstract:: |
| The standard for X-ray exposure(therapy level) was studied and set up in Secondary Standard Dosimetry Laboratory(SSDL),Beijing. The SSDL is equipped with standard dosemeters, X-ray machine, measuring rail and cart, positioning system and auxiliary devices. The parameters of X-ray radiation field and configuration of facilities used for verification of dosemeters are presented. The licence for calibration of dosemeters in China was issued by National Bureau of Metrology and the calibrating service has been,developed. |
