✦ Synopsis
The lifetimes of the highly mobile positive ions formed on ionization of cyclohexane and transdecalin solvents are extremely sensitive to radiation dose due to build up of reactive products. In cyclohexane a radiation dose of 2 x 10' J m-3 reduces the halflife to less than 50 ns mainly due to build-up of cyclohexene which reacts with a rate constant of (3.0 + 0.5) x 10' ' M-' SC'. Trace amounts of water also drastically reduce the positive-ion lifetime.
