Exposure scenarios, inadvertent intrusion, general

NCRP recommends that generic scenarios for exposure of hypothetical inadvertent intruders at disposal sites should be used in classifying waste. This recommendation is based on two considerations. First, scenarios for inadvertent intrusion can be applied to an assumed type of disposal system at any site, whereas scenarios for exposure of members of the public due to release and transport of hazardous substances to locations beyond the boundary of a disposal facility are highly site-specific and, thus, are not appropriate for use in generally classifying waste. 

Exposure Scenarios for Classifying Exempt Waste. Based on the definition of exempt waste as any waste that would be generally acceptable for disposal in a municipal/industrial landfill for non-hazardous waste, scenarios for inadvertent intrusion appropriate to this type of facility should be used in determining whether a waste would be classified as exempt.
