A pilot study of the radiation resistance of selected plastic scintillators

A study of selected plastic scintillators has been carried out with the purpose of finding at least one technique of significantly enhancing the radiation resistance of the scintillator. The authors present a status report of their current results. In summary, three basic methods can be used: (1) immerse the scintillator in argon gas, (2) an elevated ambient temperature (50 degrees C) can increase the recovery rate of the scintillator, and (3) the use of a secondary fluor which emits above 500 nm can greatly enhance the radiation resistance of a scintillator.<
