Obtaining attractive fruit
A little-known application of radioactivity is the eradication of harmful insects. The technique involves irradiating male larvae to prevent future generations of insects. This was used to great effect in the elimination of the medfly, a fly that was ravaging the fruit- and vegetable-producing countries around the Mediterranean. The method is entirely harmless for humans: gamma rays produce no radioactivity. It was the flies, not the fruit, that were affected.
