Summary Since the initial report that ultrasound radiation at diagnostic frequencies and power levels causes chromosome damage in vitro several investigators have tried unsuccessfully to confirm this. The purpose of the present study was to determine if chromosome damage could be demonstrated following fetal heart monitoring in vivo. White blood cells from ten mothers and from the cords of their newborn infants after 2 to 10 hours of fetal heart monitoring during labour were cultured and scored for chromosome damage. When the irradiated samples were compared to controls no increase in chromosome damage was found.
