ASTM于2015年发布了《核设施退役环境监测计划的标准导则》。该导则规定了核设施退役环境监测计划的制定或评估。该导则规定了:(1)退役活动开始前制定环境基线;(2)决定厂址活动的放射释放路径以及环境中的相关照射途径;(3)选择适当的采样位置及媒介,确保所有环境中的照射路径都得到合理的监测。该导则也规定了环境监测计划与其他退役厂址计划 In 2015, ASTM published the “Standard Guideline for Environmental Monitoring Program on decommissioning nuclear facilities.” The guideline provides for the development or assessment of a decommissioning environmental monitoring plan for a nuclear facility. The guidelines provide for: (1) establishing an environmental baseline prior to the decommissioning activity; (2) determining the route of radiation release at the site site and the relevant exposure pathways in the environment; (3) selecting appropriate sampling locations and media to ensure that all environments The exposure path is properly monitored. The guidelines also set out the environmental monitoring plan and other decommissioning site plans
