Increased lyoluminescence response of mannose on storage

The effect of storage on the lyoluminescence response of mannose was investigated and the dependence of the change in response on absorbed dose determined. It was found that for doses greater than the saturation value, there was an enhancement of response on storage. The hypothesis that the local concentration of oxygen near the free radical sites in the irradiated mannose is a determining factor in lyoluminescence response is postulated and discussed.
