Henry Lai: Microwave News Article Archive (2004 - )

In May, the U.S. National Toxicology Program (NTP) announced that male rats exposed to cell phone radiation developed higher rates of cancer. Soon, the NTP will explain how that might have happened.

The same RF/microwave radiation that led male rats to develop brain tumors also caused DNA breaks in their brains. Female rats —which did not have significant elevated tumor counts— had fewer DNA breaks.

All these findings are part of the same $25 million NTP project.

The NTP results provide “strong evidence for the genotoxicity of cell phone radiation,” Ron Melnick told Microwave News.

Lucas Portelli just ran over the Cheshire cat. He didn't know it was there. He's too young to appreciate how this fictional feline has held sway in the EMF-health controversy.

A little background for newcomers: the Cheshire cat is a metaphor for the lack of reproduciblity of EMF effects observed in some laboratories —but not others. It’s a favorite of those who see the study of EMFs as pathological science. The effects come and go, like the Cheshire Cat. Sometimes you see them, sometimes you don’t. EMF effects are not thought as being robust. Or more plainly, they are not to be believed.

But what if there was an unregognized confounding factor that was playing havoc with the EMF experiments? Portelli may well have found such a confounder.

Fifteen years ago Om Gandhi pointed out that children are exposed to higher levels of radiation from cell phones than adults. He was right then and he is right today. Yet, no one could blame you for thinking otherwise.

In an article published in the May issue of Harper's, Nathaniel Rich uses this putative controversy, among a number of other examples, to make the case that confusion reigns in all aspects of cell-phone research. "The brain of a child absorbs a much greater amount of radiation from a cell phone than does the brain of an adult," he writes, adding immediately after, "No, it does not."

Getting a handle on EMF and RF effects is a frustrating business. A new paper in the March 9 issue of Mutation Research from Finland's University of Kuopio tells the story. The Kuopio research group found that mobile phone radiation, at 5W/Kg, can amplify the DNA damage caused by a chemical mutagen. This is far from the first time an RF-induced genotoxic effect has been reported (see our September 3, 2008 post).

Radiation Research is a scientific journal whose primary focus is on ionizing radiation, with only a minority of papers devoted to the non-ionizing side of the electromagnetic spectrum. Its June issue, however, features five papers, all of which claim to show that EMFs of one type or another have no biological effects.

Bill Guy says that he didn’t do it, that he didn’t call NIH, that he didn’t try to shut down Henry Lai’s work on microwave-induced DNA breaks. (See "Wake-Up Call.")

In a letter to Microwave News, Guy wrote: “I most vehemently and unequivocally deny that I, or anybody that I am aware of, made any calls to NIH...”

Precautionary policies to protect children from power line electromagnetic fields (EMFs) should have been adopted years ago. It’s a no-brainer, yet health officials continue to sit on their hands.

There has long been widespread agreement that EMFs are linked to childhood leukemia. They are also likely to play a role in both brain and breast cancer as well as in miscarriages and in neurological diseases such as Alzheimer’s and ALS, also known as Lou Gehrig’s disease.

But health agencies have been unwilling to move against these largely preventable risks. It’s astonishing that those charged with promoting public health —not just electric utility executives— are the roadblocks to change.

The ability of ELF magnetic fields to damage DNA may be getting clearer (see item below) —but not so for microwaves. Over the last ten years, the battle of the Washington universities has been raging, with Joseph Roti Roti of Washington University in St. Louis at odds with Henry Lai and N.P. Singh of the University of Washington, Seattle. Roti Roti is now claiming the upper hand in the February issue of Radiation Research.
