Forword

The Basic Safety Standards for the protection of the health of workers and the
general public against the dangers from ionising radiation (Council Directive
96/29/Euratom) require national competent authorities to take into account,
when establishing clearance levels, technical guidance provided by the
European Atomic Energy Community.
The concept of clearance is very close to the concept of exemption, but the two
c oncepts relate to different stages of regulatory control. The present document 
explains the concepts and discusses their practical use from the perspective of
the overall regulatory control scheme. With regard to the concept of clearance,
so far guidance for the dismantling of nuclear installations has already been
provided by the Article 31 Group of Experts under the EURATOM Treaty.
The guidance relates to recycling of materials (metal and building rubble)
or their unrestricted reuse (metal tools, buildings).
The dismantling of nuclear installations is probably the most important area of
application of the concept of clearance, at least in terms of the volume of materials
with a potential for clearance, but the concept may also be used for a broad range
of other practices. Hence the need arose for default values for any type of material
and for any pathway of release. These have been labelled general clearance levels,
and the Article 31 Group of Experts recommends a set of nuclide- specific values
in the present document.
