There's a company in Australia called Steritech, with 3 licensed irradiation sites and they do work on beehives incidental to medical, agricultural, quarantine, pharmaceuticals, etc. applications. Their website says "Steritech irradiates beehives in order to eliminate the American Foulbrood and European Foulbrood diseases. Until Steritech offered this service any hive affected by these diseases had to be destroyed at a significant cost to the beekeeper. Now, there is a simple and cost effective method for eliminating the disease and even improve yield with the added benefit of being able to re-use the hive."
Now I'm not saying we should send our kit to Australia to be irradiated but how come Oz, with a population of 25 million has 3 facilities and the UK with a population of 60 million has one. Maybe our government and agencies don't take biosecurity as seriously as the Aussis do! They even use irradiation to sterilise archive material (documents, drawings, etc.) so that moulds etc., that could discolour the documents, are zapped; thus the archives last longer - I have not heard of that happening in the UK.
