- Abstract
- These investigations were undertaken to extend our knowledge of the radiation chemistry of two related and relatively little studied materials. In the first part of this work, polystyrene labelled with tritium, mostly on the alpha carbon, was irradiated in vacuum with x-rays. The volatile radioactive products were counted and analyzed by gas chromatographic techniques. G values (molecules formed per hundred electron volts absorbed) were obtained for tritiated products, based on energy absorbed only by the labelled monomer units in the polystyrene. These G values would apply to polystyrene in which each styrene unit had a tritium atom in it. The G's were: G(T), .00047; G(CHâ‚‚T), 00018; G for a fraction volatile at dry ice temperature but not at liquid nitrogen temperature (DIV fraction), 00095; G for a fraction volatile at room temperature but not at dry ice temperature (DINV fraction, .0061.
