Hi Emily Low frequency waves from RPW machines are transmitted into your hand. Perhaps you should avoid resting th handpiece against your tummy when operating Different manufacturers RPW can produce differing noise levels depending on the size, material and quality of their transmitters. If in doubt check with your manufacturer. If at all concerned then don't use it and then you will definitely be safe Cliff
Thanks for your reply. But the machine I'm operating is a focused shockwave. Not radial. It is alot louder than the radial ones. I did enquire with manufacturer but they no not have an answer to if it is safe for pregnant operators. That's why I'm seeking advises here... the sound to operators is stated at around 70ish dB. I wear the headphones but the fetus is not protected. Can't seems to find any other answer online.
