An Assessment of "What does photon energy tell us about cellphone safety" by Dr. William Bruno
Dr. William Bruno Assessment photon energy cellphone safety
2011/8/1
Abstract: Dr. Bruno asserts the well-known fact that cell phones radiate microwaves in the classical regime. This, he says, means that the photon energy is not relevant to assessing safety. Citing opt...
