All electrically-powered whole body vibration machines emit a small to moderate quantity of electromagnetic radiation due to Electrical Currents. If one is very ill, this could be a factor in one's healing so you need to make this a factor. Since most companies will not share the actual number of EMF %, you should know these things:
Some companies claim to shield their machines, but they cannot get rid of this radiation, as it is a feature of the motor itself that cannot be avoided. It doesn't matter if the machine is 100 volt or 220 volt, it all depends on what the motors are producing when they are turned on. A few companies now are adding shields to protect people from high EMFs, but shields are over the wires, not the motor, so they still have high EMFs even if they talk about shields. The best motors are built better and don't have the EMF problem and don't need "shields" like newer models to cover up the EMF. If it is under 1% EMF, then it is considered to be close to none and .4% is the lowest made so far. Some people are very sensitive to EMF. There are only a few companies that have very little EMF in their machines. If EMF is a concern, let me know on my quiz.
I urge everyone to get an EMF blocker and also an EMF meter. I bring my EMF meter everywhere. I can't even go to a cafe unless I check all the EMF around me from all the computers, cell phones, or whatever else is around me. I used to sit near this wall and I don't know what is behind it but the EMF was off the charts. Make sure you know about RF before buying a machine. We have been told that RF could be very dangerous to people with Pace Makers. Some models have AC motors that are from vibrating packaging machines and they turn only to one direction and that's why they cannot have the high amplitude. Also, AC motors are moistly for industrial and create strong magnetic field around them. We have also been told that this could affect the health of the bones. Is this true or not, it is for you to decide. Research EMF and make your own decision.
All machines make EMF. Even DC motors that use an AC outlet have EMF. Some might have more than others but EMF is not an issue with some of the AC models. One gets more EMF per day from telephone wires and being in a city than several of the AC wbv machines. Do not let anyone scare you away saying it will cause health problems if you step on an AC machine. It all depends on if it exceeds 1.6 watts as discussed above.
If you are going to buy a machine with an AC motor, make sure you buy one that reads no higher than a cell phone or computer. Non motor devices can make more EMF than motorized equipment. A higher dryer probably has more EMF than almost any wbv machine. If you happen to see an AC model you like, I can tell you if we tested the EMF on it or if I have heard it is very low or not an issue with buying it.
Take my quiz and I will help you choose a machine with DC or AC into consideration. I do promote certain AC models that have little EMF and I have no problem with. Again, please do not discredit AC models unless you know the facts. I was told that AC motors made EMF and that DC motors had actually ZERO EMF. This was not true until I tested the machines. This is another example of how even someone who researches these machines can get caught up into hype and lies. What I do know is how these are helping so many people, even the AC models, and I get calls and emails to my site thanking me for promoting these.
Please take my quiz here. I will give you my honest opinion on which machine I recommend after reading over your answers. If you have questions about EMF that has to do with WBV please contact me here.
BEWARE: NON FDA APPROVED MACHINES
The EPA (Environmental Protection Agency) has now established RF exposure
safety guidelines for devices emitting EMF. Before any of these can be sold on the market, each manufacturer must test their electronics and have them certified to the FCC so that it doesn't exceed the FCC established limits.
Look for SAR (specific absorption rate). This is the measure of how much of this gets absorbed in the body. On some machines, I wouldn't get closer than 3 feet next to. Others, are fine. Make sure you ask what their SAR level is on the machines HIGHEST setting. If over 1.6 watts per kg averaged over one gram of tissue, not good. If you are not turning up a machine on high it might be ok. Please check before you buy if you are concerned or simply choose a DC motor which have negligible SAR rates. SAR ratings can vary from machine to machine. You may wish to get a EMF meter and test it before you use it so you can return it if it exceeds 1.6 watts.
I am sick of every company saying they have the best one that I had to build this site. I will not sell machines that I do not approve of. I will give honest advice and reasons for my recommendations based on my research.
Ac motors have a rotating part (rotor) and a stationary part within the motor. AC motors make a magnetic field when the electricity is applied to the housing. The rotating magnetic field creates EMF by this rotation. With a DC motor, the magnetic field is not creating like an AC motor due to the applied signal and NO EMF is produced
