“…Based on in situ measurements made in the city of Ga¨vle, Sweden, the following expression can be deduced for the decrease in dose rate, D#(t), with time after deposition of radiocaesium ( 137 Cs or 134 Cs) on street pavings (Andersson et al, 2002b):…”

“…The initial contamination level on street pavings after the Chernobyl accident has been found on average to be about half of that value (Andersson et al, 2002b). G is the conversion factor from contamination level to dose rate.…”

“…A measurement series performed after the Chernobyl accident showed that the decrease in contamination level on a roof through natural weathering processes was strongly dependent on the material type (Andersson et al, 2002b). The prevailing roofing type in the Novozybkov area is asbestos sheet.…”

“…In urban areas outside of Chernobyl, radiological street contamination decreased over time due to natural weathering. However, in some areas the contamination remained on streets for up to 7 y (Andersson et al 2002). It is expected that large open permeable areas will serve as sinks of radiological contamination.…”

Wide area urban contamination events, such as after a terrorist attack or other chemical, biological or radiological disaster, pose a logistical challenge for response and remediation. The extent of contamination, both on the surface and subsurface, directly impacts the costs related to characterization sampling, decontamination, and clearance sampling (e.g. personnel, consumables and waste management). Modeling tools that can predict the location and magnitude of contamination may allow for a more efficient allocation of key resources since wide area incidents may be very costly, and take an extended amount of time, to remediate. This paper identifies 27 existing water models that are able to simulate hydraulic, hydrologic and water quality processes and discusses the necessary adjustments to running the models during remediation activities. It also highlights how these features relate to the unique considerations encountered in the homeland security sector and discusses ongoing research needs.

“…In most of the settlements subjected to radioactive contamination the air dose rate above solid surfaces is at now pre-accident level however walls have not received the same weathering as roofs. Radiocaesium on asphalt surfaces caught up in street dust is less than 10% of initial deposits (IAEA, 2006;Andersson et al, 2002).…”
