Evidence for Nonthermal Effects of Microwave Radiation: Abnormal Development of Irradiated Insect Pupae
Russell L. Carpenter, Elliot M. Livstone · 1971
Microwave radiation caused death or abnormal development in 76% of exposed insects while radiant heating under the same thermal conditions left development normal.
Plain English Summary
Scientists exposed mealworm beetle pupae to 10 GHz microwave radiation and found that 76% either died or developed abnormally, compared to 90% normal development in controls treated the same way without microwave power. When researchers duplicated the thermal conditions using radiant heating, development of the pupae was normal, which the authors present as evidence for a nonthermal effect of the microwaves.
Why This Matters
This 1971 study reports evidence of a nonthermal effect of microwave radiation on insect development. Early pupae of the mealworm beetle were irradiated at 10 GHz CW: 25% died and 51% developed abnormally, and only 24% developed normally, compared to 90% normal development in controls treated the same way without microwave power. When the thermal conditions were duplicated by means of radiant heating, development of pupae was normal. In half of the abnormal animals, the front half had undergone metamorphosis to form a normal beetle head and thorax but the hind part remained in the pupal state.
