"research has shown that sterilizing old beehive frames with gamma rays before reusing them cuts down the risk of colony collapse"
Where would a beekeeper gain access to a gamma source?
Where would a beekeeper gain access to a gamma source?
Or someone will go into business as a door-to-door gamma irradiation service: The truck with the lead-lined box arrives at the appointed time, you hand them the frames along with $x per frame, they irradiate them for you and hand them back.
If it's more efficient to truck the frames to the source... well, that works too. A lot of these industrial beekeepers routinely truck entire flatbeds full of hundreds and hundreds of beehives to farms around the country. Occasional stops at the cities where the hive irradiators are available might not be such a big deal.
