Getting rid of pests by sterilization
Doses of several hundreds of grays are used in the food business to destroy the microorganisms or, as can be seen in this picture, the insects which pose a threat to humans. The photograph shows male larvae of Mediterranean flies that have been exposed to a radioactive source of cobalt 60. The flies are thus sterilized by a dose of several hundred grays. Once released, the species’ ability to proliferate is dramatically reduced.
