1.1本规程涵盖了确定现场是否准备好关闭所需的步骤，重点是一般采样技术，以及如何确定是否已达到商定的补救水平。 1.2本实践中至少使用了统计程序。 1.3本标准惯例既不涉及放射性废物场地，也不涵盖现场可能发生的每种情况。它确实涵盖以下一般采样技术:土壤采样、建筑物和设备的刷卡采样、表面蓄水、垃圾堆和分层储罐。它不包括滚筒取样、一般水取样和监测井及其施工。 1.4 本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，以确定监管限制的适用性。

1.1 This practice covers the steps necessary to determine if a site is ready for closure with emphasis on general sampling techniques and how to determine if the agreed upon level of remediation has been achieved. 1.2 A minimum of statistical procedures is used in this practice. 1.3 The standard practice does not address radioactive waste sites nor does it cover every situation that can occur in the field. It does cover the following general sampling techniques: soil sampling, swipe sampling of buildings and equipment, surface impoundments, waste piles, and layered tanks. It does not cover drum sampling, general water sampling and monitoring wells and their construction. 1.4 This standard does not purport to address all safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices to determine the applicability of regulatory limitations prior to use.
