Technology works by disrupting food decay

IRRADIATION works by ionising molecules in the cells that make up organisms such as bacteria, and by disrupting food decay mechanisms.

But environmental groups worry about the growth in use of deadly radioactive sources needed to produce the high-energy irradiating gamma rays, what happens to the waste and the safety of the irradiation plants.
