Absence of Significant Short-Term Electromagnetic Bioeffects in Giant Algal Cells Exposed to CW and Pulse-Modulated X-Band Bursts

Giant cells of the algae Chara brauni and Nitella flexilis were exposed to continuous wave and pulse-modulated bursts of X-band microwaves and the vacuolar potential was monitored for immediate radiation-correlated offsets. No such offsets were observed despite a resolution of approximately 5 in 10⁵, and despite the wide variety of frequencies, power levels, and pulse protocols employed.
