Boy (or gal), do I have news for you...

More seriously, whether the author is right or wrong (I cannot judge), assessing these things scientifically is warranted. You cannot simply appeal to emotions or alleged common sense.

Irradiated doesn't even mean radioactive. It's like saying I don't want to be set on fire, so I won't eat cooked food.

I think the author would have no problem with mushrooms from Chernobyl given that they were under a specified level of activity.
