The liquid scintillation process is the conversion of the energy of a radioactive decay event into photons of light. Photomultiplier tubes (PMT’s) are used to detect and convert the photons i Liquid scintillation counting is an analytical technique which is defined by the incorporation of theradiolabeled analyte into uniform distribution with a liquid chemical medium capable of converting5 Laboratoire de Physique Statistique de l ’ENS (Paris). see: « The discovery of superfluidity » J.

The atomic number of helium is 2, meaning each atom of helium has two protons.. Helium has the lowest melting point and boiling point of the elements, so it only exists as a gas except under extreme conditions.. CSULB Radiation Safety Office. March, 2013. Welcome. This PowerPoint presentation provides an overview of how to use the LSC for qualitative purposes such as for contamination surveys. You will be provided detailed instructions on specific LSC counting methods and materials by experienced personnel in your particular lab. Proper use of the LSC is monitored by supervisor, the IRUA holder for whom you work and by Radiation Safety as a part of their audits of your radiation safety program compliance..
