What can be done to prevent contamination from re-suspending in the air during a nuclear or biological incident?

Wetting down exposed surfaces is a critical step in preventing contamination from re-suspending in the air during a nuclear or biological incident. This approach helps to suppress dust and particulate matter that could otherwise become airborne, thereby reducing the risk of inhalation or spread of hazardous materials. The moisture created by wetting the surfaces effectively binds contaminants to the ground, making it much less likely that they will become airborne. This is particularly vital in situations where biological agents are present, as it minimizes exposure to individuals in the vicinity.

In contrast, waiting for assistance from specialized teams may be necessary for safety and expertise but does not actively mitigate the risk of re-suspension in the interim. Evacuating the area quickly could be a necessary response but would not help curtail the contamination within the environment itself while individuals are present. Using dry cleaning methods could inadvertently disperse particles back into the air, further aggravating the situation instead of resolving it. Thus, wetting down exposed surfaces serves as a proactive and effective solution in such scenarios.
