Re: Doppler advice

Fetal dopplers do not expose babies to radiation. They expose babies to ultrasonic waves. Same thing bats use to echolocate. At the low frequencies ultrasounds & dopplers are used at (when used correctly) there is not a concern for overheating or cavitation. (Bubbles on a molecular level)
