Exposure limits set for microwave radiation assume that any biological effects result from tissue heating: non-thermal effects have been reported but remain controversial. We show here that prolonged exposure to low-intensity microwave fields can induce heat-shock responses in the soil nematode Caenorhabditis elegans. This effect appears to be non-thermal, suggesting that current exposure limits set for microwave equipment may need to be reconsidered.
