Abstract
Radiological Dispersal Device (RDD) characterization is an area of active research for security and military purposes. Defence Research and Development Canada (DRDC) has been conducting research in this area since 2003. The evaluation of RDD consequences, however, is difficult to do in practice due to practical and safety issues around the use of radioactive isotopes that are considered threats in RDDs. At present, theoretical models are heavily relied upon to characterize and describe RDD dynamics, and to derive useful quantities such as airborne concentration and ground deposition. In order to build up experimental data on real-world RDD effects, DRDC Ottawa Research Centre led a series of Full-Scale RDD (FSRDD) trials in 2012 that used a short-lived radioactive source (140La) as a surrogate for threat isotopes.
