The effectiveness of PRANAN devices has been tested using MORA bioresonance technology. Developed by Dr. Franz Morell and engineer Enrich Rasche.

Bioresonance uses electromagnetic waves to keep the body in balance. Scientists Fritz Popp and Ross Adey have described these electromagnetic signals as a means of cellular communication.

This simple test shows the changes that occur in the body when it receives the electromagnetic radiation emitted by the cell phone at the time of receiving a call, and the same, but when the PRANAN protection device is placed on the cell phone.
