摘　　要：叙述了估算强流质子直线加速器横向屏蔽的方法。束流能量处在GeV能区时,使用Moyer模型进行计算;在1GeV以下,使用基于点源视线法的Tesch公式。在1W/m的束流损失情况下,对50～3000MeV束流能量范围内的横向屏蔽厚度进行了计算,并给出推荐值。A simple method for the estimation of the transverse shielding for intensebeam proton linac was described briefly. For beam energy at GeV range, Moyer model was used for calculation, below 1 GeV, Tesch＇ equation was used. In the case of 1 W/m beam loss, transverse shielding thicknesses were calculated in the beam energy range 50 to 3 000 MeV, and the recommended values were given.
