Our comments:

Seller claims this paint will provide 37dB of attenuation from one coat, equivalent to over 99% effective, and even more with two coats.

They don’t indicate whether this product needs to be earthed in order to be effective, but one of the Amazon reviewers commented that earthing was required.

Keys, wallet, cell phone . . . ready to go! Cell phones have become ubiquitous fixtures of twenty-first-century life—suctioned to our ears and stuck in our pockets. Yet, we’ve all heard whispers that these essential little devices give you brain cancer. Many of us are left wondering, as Maureen Dowd recently asked in the New York Times, “Are cells the new cigarettes?” 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), coming not only from cell phones, but many other devices we use in our homes and offices every day.

Dr. Blank arms us with the information we need to lobby government and industry to keep ourselves and our families safe.
