Sterilization
Gamma Irradiation Program.
Hi Everyone, during the spring each year we will be facilitating a beekeeping equipment sterilization event at Sterigenics, 75 Tilbury Road, Salem, NJ 08079. As a larger group we are able to combine pallet loads to meet feasible volumes for more efficient biosecurity controls. Current pricing from Sterigenics is US$248.80 a pallet and is cost effective once we meet ten pallets or more. This seasons date is set for 22nd March 2022. Turn around is usually about one week. We will be accepting wrapped equipment to combine loads from the 1st through to the 21st of March at our delivery yards. Any questions please contact Tim@extractandbox.com

About Gamma Irradiation
Gamma irradiation is a short wave length high energy form of ionizing radiation, it is an effective sterilization utilizing the industrialized radioisotope Cobalt 60.
Gamma rays are photons, they travel at the speed of light and have zero charge or mass. Gamma rays have enough energy to detach electrons from atoms or molecules in the matter in through which they pass, therefore ionizing the atom causing a reaction with the cells of organic matter.
Cobalt 60 is created by charging natural Cobalt 59 slugs with a single neutron, this is done by introducing the slugs into a nuclear power reactor for up to 24 months where the Cobalt absorbs the additional neutron. As an unstable atom, Cobalt 60 emits electrons and gamma rays. This energy release is not high enough to become reactive, yet strong enough to be an effective sterilizer.
The level of ionizing radiation absorption is measured in gray and defined as joules over mass, represented as kGy. The Gamma irradiation program was established to meet the sterilization level of 10kGy to inactivate American Foul Brood. On completion of the irradiation service we receive a certificate of processing. The March 2021 irradiation actual dose was 16.5kGy
Our current literature search is listed below. Not all the infections listed below are related to beekeeping, however they are of interest in explaining gamma irradiation as a sterilizing tool.
