Overpowered brings readers, in accessible and fascinating prose, through the science, indicating biological effects resulting from low, non-thermal levels of non-ionizing electromagnetic radiation (levels considered safe by regulatory agencies). Radiation that comes not only from cell phones, but many other devices we use in our homes and offices every day. It is generally accepted that there should be a limit on exposure of the public to EMF. However, industry pushes the envelope. Dr. Blank advises applying the precautionary principle when it comes to demonstrably hazardous EMF--and teaches us how we can take steps in our daily lives to reduce exposures.
