In this work we have prepared liquid scintillation detectors using organic scintillation materials such as Naphthalene and Anthracene, each one dissolved in the organic solvent ( Xylene ). then we have measure the Net Area Under Peak, for wide range of concentrations of the organic scintillation solutions. We get best concentration (which gives maximum value of scintillation) of liquid scintillation detector prepared from Naphthalene solute in Xylene is)40g/l( and for scintillation detector prepared from Anthracene solute in the Xylene is (1.4g/l ). Then in order to study effect of quenching on these prepared detectors, we added different concentrations of quenchers to the organic scintillation solutions at the optimum value of concentration.
