Irradiation, sprout-inhibiting effects

For sprout inhibition of onions and potatoes by irradiation, conditioning of bulbs and tubers at optimal temperatures and relative humidities and for a time period until they are at the dormant stage would make the irradiation process more effective (6). 

Another potential application of radioactive species is in food preservation (Figure 18.4). It is well known that gamma rays can kill insects, larvae, and parasites such as trichina that cause trichinosis in pork. Radiation can also inhibit the sprouting of onions and potatoes. Perhaps most important from a commercial standpoint, it can extend the shelf lives of many foods for weeks or even months. Many chemicals used to preserve foods have later been shown to have adverse health effects, so irradiation is an attractive alternative. Finally, irradiation can destroy microorganisms such as E. coli (which explains its use in treating beef) and anthrax (which explains its use in sterilizing suspected mail).
