Neurosurgeon Dr. Leif Salford shows us that it only takes 0.02-0.04 microwatts per kilo of cell phone radiation at 2 hours per day for 28 days to significantly weaken the blood-brain barrier (BBB) in lab rats.
The ill effects from a compromised BBB are significant. Not mentioned in the video is that all fine membranes in the body also become compromised. These include the cornea, intestines, and the placenta.
It is clear that cell phones can also have a "second-hand smoke" effect in that even if you are nearby a cellphone you can have your BBB compromised. Remember, it's all about the prolonged exposure over time.
