I am sure someone knowledgeable will help me out here concerning the irradiated/not irradiated comb. As I understand it, this was a spring/summer/fall loss, not over a winter, with a commercial pollinator. Plus, it was an estimate, not an actual count.I may just remember the initial reports, but there may have been follow-up studies of a more scientific nature.
