摘要：
An electron-positron collider (LEP) has recently been put into operation at CERN. Two 46 GeV beams circulate around the 27 km accelerator ring and these produce intense synchrotron radiation with photon energies up to more than 1 MeV. A lead shield 8 mm thicks has been provided in most places around the vacuum chamber to minimize radiation damage to sensitive machine components. Monte-Carlo techniques using a modified version of MORSE have been used to estimate dose-rate levels in the tunnel due to radiation escaping from the vacuum pipe and scattered by magnets and the tunnel walls. The results have been confirmed by dosimetry measurements.
