Abstract
Irradiated water and the headspace above it has been analysed using a novel hydrogen‐specific electronic sensor, calibrated with standard hydrogen dilutions. The results demonstrate that this detector is well capable of distinguishing between irradiated and non‐irradiated water through the quantitative determination of the hydrogen generated during irradiation. This hydrogen diffuses away within 12 h if the water is left in an open vessel. The potential application of the detector for monitoring irradiated food is therefore limited to packaged or solid foods which retain the characteristic hydrogen marker.
