Six typical forms of drywall construction have been tested as barriers against primary and secondary dental x-radiation. It is concluded that this widely used type of wall construction is generally effective for this purpose, but with a heavy workload two thicknesses of wallboard on each side of the wall are required to provide a sufficient barrier. In general, no lead need be incorporated in the walls.
六种典型的石膏板结构已作为阻挡牙科一次和二次X射线辐射的屏障进行了测试。得出的结论是，这种广泛使用的墙体结构通常对此目的有效，但工作量较大时，需要在墙体两侧各使用两层墙板才能提供足够的屏障。一般来说，墙体中无需加入铅板。
