A Report on Non-Ionizing Radiation

Unremarkable science can sometimes tell a remarkable story. Two papers that were published in the last few weeks —and passed mostly unnoticed— have important, though very different, backstories.

One offers a surprising glimpse of change in the usually static field of RF research, while the other shows how much has stayed the same over the last many years.

Yet, in the end, they offer the same well-worn message, always worth repeating: Those who sign the checks, run the show.

The two papers come 30 years after Henry Lai and N.P. Singh began an experiment at the University of Washington in Seattle that would set off alarm bells across the still-young cell phone industry —and the U.S. military. Lai and Singh would show that a single, two-hour exposure to low-level microwave radiation (today, we’d say RF) could lead to breaks in the helical strands of DNA in the brains of live rats.

Narendra P. Singh, known to friends and colleagues simply as NP, died last December at the age of 69. When his family wrote to me with the news, Singh’s wife asked me not to publish a tribute or an obituary at that time. I honored her request, but now, after a decent interval, I break my silence, in part to make good on a promise and to settle some unfinished business.

Singh was a proud and honest man; he was also gentle and unassuming. “He cannot tell a lie, even a white lie,” Henry Lai, his long-time collaborator at the University of Washington in Seattle, told me years ago. Perhaps most of all, Singh was a meticulous experimentalist who believed in the power of science.

More and more scientific societies are considering adopting disclosure rules to shed light on potential conflicts of interest. Environmental Science & Technology reports that the American Geophysical Union and the American Meteorological Society are weighing such a policy, while the Society for Risk Analysis is now requiring authors to sign conflict-of-interest statements. These three groups publish Geophysical Letters, Journal of Climate and Risk Analysis, respectively.

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.
