中文摘要	Using the Monte Carlo code MCNP4B, skyshine of 9 MeV electron linear accelerator was calculated with a multistep method combining the split and roulette variance reduction technique. Dose distribution of the skyshine was measured around the accelerator room. Results of the Monte Carlo simulation, empirical formulas and dosimetric measurement were compared and analyzed. In conclusion, the dosimetric measurement agrees with the results computed by Monte Carlo method reasonably, but deviates with computational results from empirical formulas. It shows that Monte Carlo method is a good way to analyze skyshine.
