The resulting photons are amplified after being converted into electric pulses, and are finally displayed as individual counts. ]]></termNote><termCreatedDate>2026-03-30 20:21:54</termCreatedDate><relation><relationType>UF</relationType><termId>31304544</termId><termName>LSC</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31304545</termId><termName>counting, liquid scintillation</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31298665</termId><termName>analysis and testing techniques</termName><termType>PT</termType></relation></term>  </Zthes>
