Reduction of the background magnetic field inhibits ability of Drosophila melanogaster to survive ionizing radiation.

The effects of exposure to an environment where the background magnetic field (BMF) has been reduced were studied on wild-type Drosophila melanogaster by measuring its ability to survive a single exposure to ionizing radiation (IR) during its larval stage. The experimental design presented shows a timeframe, IR dose, and BMF parameters that will cause a significant and reproducible reduction of survival on this insect model. These results suggest that BMFs may play a fundamental role in the recovery or harm of a biological system that is exposed to single doses of IR.
