skos:definition "A physical obstruction that prevents or inhibits the movement of people, <br/>
radionuclides or some other phenomenon (e.g. fire), or provides shielding <br/>against 'radiation'.<br/>
See also 'cladding (material)', 'containment', 'defence in depth'.<br/>
<i><b>intrusion barrier.</b></i> 'Components' of a 'repository' designed to prevent <br/>inadvertent access to the 'waste' by humans, animals or plants.<br/>
<i><b>multiple barriers.</b></i> Two or more natural or engineered 'barriers' used to <br/>isolate 'radioactive waste' in, and prevent 'migration' of radionuclides from, <br/>a 'repository'.<br/>
<b>!</b> The term ‘chemical 'barrier'’ is sometimes used in the context of 'waste disposal'<br/>
to describe the chemical effect of a material that enhances the extent to which <br/>radionuclides react chemically with the material or with the host rock, thus <br/>inhibiting the 'migration' of the radionuclides. As defined above, this is not <br/>
strictly a 'barrier' (unless the material also constitutes a physical 'barrier'), but <br/>the effect may be equivalent to that of a 'barrier', and it may therefore be <br/>convenient to regard it as such.<br/>" (en)
