Samples of chicken, prawns, cheeses and spices were irradiated on the Harwell electron linear accelerator HELIOS at 20 MeV to assess mechanisms for the induction of radioactivity. The induced radioactivity was measured using a lead shielded Ge(Li) gamma-ray spectrometer, and the results were compare

✦ Synopsis
Explicit expressions are presented for calculating specific activities induced in food by electron and photon irradiation.
In addition, sets of calculated values are tabulated for neutron fluxes produced from moderation and thermalisation of photoneutrons generated within the food. Evaluations of the prescriptions presented are compared with existing experimental measurements of activities induced by electron and photon irradiation under artificial conditions to induce measurable activities.
Good agreement is obtained.
