随着越来越多的数太瓦（1012 W）和拍瓦（1015 W）激光相互作用设施正在建设中，需要详细了解潜在的放射性危害，其对人员的影响是一个重大问题。为实现这一目标，正在一些设施进行试验。本文介绍了最近完成的工作，在CCLRC卢瑟福阿普尔顿实验室，在那里的光子剂量高达43毫西弗在1米每拍摄的火神petawatt激光系统已在调试研究期间进行了测量。它还概述了为遵守《1999年电离辐射条例》（IRR 99）而在设施上设置的屏蔽装置，将人员的剂量维持在1 mSv/yr-1以下，并尽可能低（ALARP）。
With the increasing number of multi-terawatt (1012 W) and petawatt (1015 W) laser interaction facilities being built, the need for a detailed understanding of the potential radiological hazards is required and their impact on personnel is of major concern. Experiments at a number of facilities are being undertaken to achieve this aim. This paper describes the recent work completed on the Vulcan petawatt laser system at the CCLRC Rutherford Appleton Laboratory, where photon doses of up to 43 mSv at 1 m per shot have been measured during commissioning studies. It also overviews the shielding in place on the facility in order to comply with the Ionising Radiation Regulations 1999 (IRR99), maintaining a dose to personnel of less than 1 mSv yr−1 and as low as reasonably practicable (ALARP).
