Iowa senator Tom Harkin recently became chairman of the Senate Health, Education, Labor and Pensions Committee, following the death of Senator Ted Kennedy. On Monday, Harkin vowed to look into the possibilities of cancer risks from mobile phone use. He said he was concerned that nobody was able to definitively prove that mobile phones could not cause cancer.
"I'm reminded of this nation's experience with cigarettes. Decades passed between the first warnings about smoking tobacco and the final definitive conclusion that cigarettes cause lung cancer," Harkin said. It is estimated that 4 billion people worldwide use mobile phones regularly.
Harkin called a hearing of the Appropriations Committee's Subcommittee on Labor, Health and Human Services, and Education, to examine the issue on Monday. "I will pursue this beyond this panel, with the National Institutes of Health," he said afterward.
However, Harkin should be aware that an enormous amount of research has been conducted already on this issue, and no link has ever been found to prove that mobile phones do cause cancer. Simply saying that nobody has been able to disprove it does not make it more plausible, and it is slightly concerning at least that an elected Senator would pursue something on the grounds that nobody could disprove its existence - but it isn't surprising.
Of course, there are reports occasionally that do show that there "might" be links in cases, and just recently the Environmental Working Group showed that radio wave emissions vary from one mobile phone brand to the next. Even with this taken into account however, all the research has shown that mobile phones do not emit waves capable of damaging DNA in cells in a human body.
"This part of the spectrum is known as non-ionizing radiation," Linda Erdreich of science and engineering firm Exponent, said at the hearing. Pennsylvania Senator Arlen Specter, however, made the same leap as Harkin and repeatedly asked Erdreich whether Science had conclusively proved there are no connections - which is a misunderstanding of exactly what Science does.
"Your statement that it is hard to prove a negative is right on," Erdreich replied. Specter replied: "What comes through to me is that we just don't know what the answer is."
