In 2012, Defence Research and Development Canada, in partnership with a number of other Canadian and International organizations, led a series of three field trials designed to simulate a Radiological Dispersal Device (RDD). These trials, known as the Full-Scale RDD (FSRDD) Field Trials, involved the explosive dispersal of a short-lived radioactive tracer ((140)La, t1/2 = 40.293 h). The FSRDD Field Trials required a significant effort in their planning, preparation, and execution to ensure that they were carried out in a safe, efficient manner and that the scientific goals of the trials were met. The discussion presented here details the planning and execution of the trials, outlines the relevant radiation safety aspects, provides a summary of the source term and atmospheric conditions for the three dispersal events, and provides an overview of the measurements that were made to track the plumes and deposition patterns.
2012年，加拿大国防研究与发展局与其他一些加拿大和国际组织合作，开展了一系列三场实地试验，旨在模拟放射性散布装置（RDD）。这些试验被称为全尺寸RDD（FSRDD）实地试验，涉及一种短寿命放射性示踪剂（（140）La，t1/2 = 40.293小时）的爆炸散布。FSRDD实地试验在规划、准备和执行方面需要付出巨大努力，以确保试验以安全、高效的方式进行，并实现试验的科学目标。此处的讨论详细介绍了试验的规划和执行情况，概述了相关辐射安全方面，总结了三次散布事件的源项和大气条件，并概述了为追踪羽流和沉积模式而进行的测量。
