Abstract
REPORTS from this laboratory1–4, afterwards confirmed elsewhere5, have shown non-thermal effects of radio-frequency on living organisms and non-living material. To preclude heat in these experiments, the radio-frequency was pulsed with pulse widths in the (μsec range, and the duty cycle usually was less than 1 per cent. In these conditions any rise in temperature could be controlled so as to be virtually undetectable.
