"All cancer agents act by disrupting chemical bonds. In a classic 2001 op-ed LBL physicist Robert Cahn explained that Einstein won the 1905 Nobel Prize in Physics for showing that cell phones can’t cause cancer. The threshold energy of the photoelectric effect, for which Einstein won the prize, lies at the extreme blue end of the visible spectrum in the near ultraviolet. The same near-ultraviolet rays can also cause skin cancer. Red light is too weak to cause cancer. Cell-phone radiation is 10,000 times weaker."
