The theoretical concept is based on the measurement of the dielectric contrast between water and the host material in the microwave frequency range, and is successful up to 2 cm in depth. In conservation, this method has been usefully employed for determining by non-invasiveway the moisture and salts content inside materials. ]]></LexicalValue></ScopeNote><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31317505" xml:lang="en">	<LexicalValue>EFD</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31317504</USE></NonPreferredTerm><HasHierRelConcept Role="BT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31304556</HasHierRelConcept><HasRelatedConcept Role="RT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31383844</HasRelatedConcept></ThesaurusConcept></Thesaurus>
