Five devices were tested for the amount of optical radiation they emitted. Recommended values can be exceeded with a workload of 17 to 81 applications in any 167-minute period. Some procedures, such as close viewing distances, direct view applications, and treating the anterior teeth may increase the exposure to the user.
对五台设备发出的光辐射量进行了测试。在任何167分钟时间段内，若工作量为17至81次应用，则可能会超过推荐值。一些操作，如近距离观察、直视应用以及治疗前牙，可能会增加使用者的暴露量。
