The membrane potential of Characean cells exposed to amplitude-modulated, low-power 147-MHz radiation

The membrane potential of isolated cells of Chara braunii or Nitella flexilis was monitored while the cells were exposed, at nominal power densities from 2 to 1,000 W/m2, to 147‐MHz radiation amplitude modulated at frequencies from 4 to 64 Hz. Phase‐sensitive detection was used to seek radiation‐cor...

description The membrane potential of isolated cells of Chara braunii or Nitella flexilis was monitored while the cells were exposed, at nominal power densities from 2 to 1,000 W/m2, to 147‐MHz radiation amplitude modulated at frequencies from 4 to 64 Hz. Phase‐sensitive detection was used to seek radiation‐correlated changes in the membrane potential, and none were apparent under any of the conditions used in this investigation.
