The link above shows some data concerning food irradiation and the doses
used for disinfestation of several organisms. The killing dose shown for
insects is in the 0.22 to .0.93 kGy range. For viruses, it is in the 10 to
40 kGy range.
We have a large food processing plant not far from here, using Co-60 to
irradiate raw materials that go into cake mixes and other food products.
I routinely monitor this plant for radiation leakage, but have found none so
far, but the same survey did turn up a particular problematic industrial
X-Ray unit is a manufacturing plant in the same industrial park. This "leak"
could be detected 3/4 mile away. Interestingly, the safety manager
immediately tested the operator's TLDs and reportedly found no exposure.
Somewhere I read that the largest irradiators in use are to kill natural
occurring anthrax on wool.
