Abstract
Sonicated egg phosphatidylcholine vesicles loaded with ^24^Na^+^ were exposed at 20mW to a frequency‐modulated (3 Hz) microwave field in the range of 2350 to 2550 MHz, or at 80 mW to a 2450‐MHz CW (continuous wave) field, in a waveguide. The vesicle suspension absorbed microwaves at about 1 mW/ml and 25 mW/ml (CW experiment). The average temperature change of the irradiated suspension was < 0.1 °C from ambient. Leakage of ^24^Na^+^ from the vesicles for up to 19 hours was measured. No difference was noted in the movement of ^24^Na^+^ from the vesicles in the irradiated and control dispersions.
