FWIW, Norway irradiates almost all of its imported spices, and has been doing so since 1982. It's done using gamma rays. The technique is actually recommended by the WHO and the UN's FAO. Wikipedia says "a large amount of independent research has confirmed irradiation to be safe [5][6][7][8][9]" and also contains the gem "Irradiated food does not become radioactive, just as an object exposed to light does not start producing light." https://en.m.wikipedia.org/wiki/Food_irradiation https://en.m.wikipedia.org/wiki/Food_irradiation
