Ionizing radiation metrology 

Authors: S. Visetpotjanakit and S. Udomsomporn Publication Type:17th International Congress of Metrology published by EDP Sciences, 2015 Year: 2015 Abstract:  To determine Sr-90 activity in environmental samples advanced cerenkov counting using liquid scintillation counter has been widely investigated. Separated Y-90 in equilibrium with Sr-90 in a solution can be counted using a Cerenkov measurement without scintillation In […]

Khrautongkieo Publication Type:18th International Congress of Metrology, 11004   Year: 2017 Abstract:  A rapid method to determine 137Cs in seawater using Cu-hexacyanoferates ion exchanger has been developed and verified for purpose of Thailand routine and emergency environmental radiation monitoring. The Cu-hexacyanoferrate supported cotton-wound cartridge filters were used to absorb 131Cs from spiked synthesis
