A simple efficient liquid scintillator for counting aqueous solutions in a liquid scintillation counter
摘要：
A modification of the naphthalene-dioxane-PPO liquid scintillator has been described which will allow up to 3.0 ml of an aqueous solution to be counted. The efficiency of this method in the presence of 1.0 ml water is 65.6% for C 14 and 11.7% for tritiated water. This liquid scintillator has been used to count carbon-14 and tritium in urine, plasma, and liver homogenate. The effect of isotope concentration, solute concentration, and the presence of acids and bases on the count rate has been investigated.
