title: A simple method for measuring 125I by liquid scintillation counting.
abstract: Scintillation solutions containing surface active substances, soluble in Toluene, could be used for efficient counting of 125I. The use of Triton X-114 in the proportion 30% v/v with a Toluene-2,5-Diphenyloxazole basic scintillation solution, provides a method for the measurement of liquid and solid samples with 50% efficiency and aqueous sample capacity up to 25%.
