[en] The system to be considered in any generic methodology to calculate ex situ doses deriving from contaminated wood encompasses its industrial and domestic utilisation in the country of origin and/or in a country importing contaminated wood. One feature of the system to be considered is that all potentially exposed people, whether in an industrial or domestic situation, are not registered radiation workers and, in radiological protection terms, are to be considered as members of the public. The exposure that a person receives is a function of the use of the wood or wood product. The radiological significance of each technology and relevant exposure pathways, whether industrial or domestic, needs to considered individually. To achieve this, detailed scenarios of human exposure must be defined for each technology and relevant exposure pathways. (ln)
