6.59. In accordance with Ref. [22], “those living around the site” should be considered receptors in human intrusion scenarios. This does not mean, however, that the intruder should be automatically excluded from consideration. A distinction should not be made between the intruder and the residents. Indeed, these could be the same persons in the case of people living on top of a former site about which knowledge has been lost. Instead, a distinction should be made between the normal behaviour of people living near or even on the site, and events with a short duration and/or low probability of affecting a small number of people (such as road construction activities). Regarding the latter as ‘industrial accidents’ would not require application of the same dose criteria to the intruders in these cases as those applied to the residents near or on the site. In accordance with this distinction, the actual contact of the receptor with the waste may be considered in scenarios, and the dose criteria for intrusion, as set out in Ref. [2], may be applied to the resulting exposure if this event is deemed to be possible in a normal residential situation.
