Liquid Scintillation Fluid Policy
The University’s Radiation Safety Executive Committee has mandated that only biodegradable liquid scintillation counting fluid with a flash point >140o F can be used unless special approval is obtained from the Executive Committee.
Scintillation fluids based on toluene or xylene will no longer be available except by special order. Principal investigators who are authorized to use radioactive materials or are applying for such use may petition the Executive Committee for a scintillation fluid exception. Petitions must be submitted in writing and clearly state why the use of a scintillation counting fluid with a flash point < 140o F is required for their scintillation counting needs.
