The radiation source in the facility in Sydney Australia is Cobalt 60 producing
gamma radiation. Hive equipment is treated at 15 kilograys.

A previous comment on this topic suggested that all AFB infected combs should
be burnt. With the above level of irradiation AFB spores are sufficiently loosened
for bees to be able to remove the scales. Therefore the frames can be retained for
further use.

The heat and irradiation treatment causes any honey residue to run out of the
boxes and make things very messy.

All hive equoipment and frames have to be free from honey & double bagged or
stretched wrapped.
