The director of a leading US cancer research institute has sent a memo to thousands of staff warning of possible higher risks from mobile phone use.
Ronald Herberman, of the University of Pittsburgh Cancer Institute, said users should not wait for definitive studies on the risk and should take action now.
He said children should use mobiles in emergencies only and adults should try to keep the phone away from the head.
No major academic study has confirmed a link to higher brain-tumour risks.

Dr Herberman said his warning was based on early findings from unpublished data.
“We shouldn’t wait for a definitive study to come out, but err on the side of being safe rather than sorry later,” he says.
“I am convinced that there are sufficient data to warrant issuing an advisory to share some precautionary advice on cell phone use,” the memo says.
Dr Herberman’s warning to 3,000 staff says children should be protected as their brains are still developing.
He lists tips including switching sides regularly while talking on mobiles.
A major six-year research study in the UK said last year that there were no short-term adverse effects to brain and cell function from mobile phone use.
However, the UK Mobile Telecommunications and Health Research Programme said there was a “hint” of a higher cancer risk in the long term and that its research would look into the effects over a 10-year period.
Programme chairman Professor Lawrie Challis said: “We can’t rule out the possibility at this stage that cancer could appear in a few years’ time.”
An earlier UK report said in 2005 that mobile phone use by children should be limited as a precaution – and that under-eights should not use them at all.
Mobile phones emit radio signals and electromagnetic fields that can penetrate the human brain, and some campaigners fear that this could seriously damage human health.
A third of the 20 million American preteen children between the ages of 8-12 already have a cell phone and that level will jump to nearly half by 2010, according to industry experts.
With so many parents using pre-paid and other affordable options to arm their children with cell phones, experts are emphasizing that it’s important to make sure that children know how to use those cell phones to be safer this summer.
Nicholas P. Sullivan, author of a March 2008 study based on more than 110,000 interviews with prepaid and other cell phone users (who were asked about emergency/safety use of wireless phones) and the 2007 book “You Can Hear Me Now: How Microloans and Cell Phones Are Connecting the World’s Poor to the Global Economy,” said:
“In a world of split custody arrangements, households in which both parents work, and other factors, the low-cost prepaid phone has made it possible for parents to extend to their children the same kind of ’safety blanket’ that they rely on in emergency situations. We know from research that more and more adults are placing emergency calls from cell phones. Given that younger, tech-savvy Americans are even more inclined to rely on wireless phones, it is imperative that parents take the time to make sure children understand how to use the phone to be safe.”
“Every day, nearly a quarter of a million emergency calls are placed to 9-1-1 from cell phones and we expect to see children making a bigger share of those calls as cell phone use among youths becomes even more prevalent” said David Aylward, director and founder, COMCARE Emergency Response Alliance — a nonprofit educational and advocacy group of more than 100 organizations representing emergency responders nationwide.
“Children need to be taught that the cell phone is a tool, not a toy. It can play an important role in emergency situations involving children, but only if their parents have taken the time to teach kids what they need to know.”
Sullivan and Aylward outlined the following three recommendations for enhanced summer safety for children with cell phones:
1. Teach your child to push “9-1-1″ and then the cell phone’s “call” or “send” button — in an emergency. Explain that this is a very serious thing and that placing the call will bring a police officer, firefighter or EMT to the scene. Explain that “emergency” for 9-1-1 means threat to body or life — “afraid you will be hurt.
” Don’t assume that because you know how 9-1-1 works that your child also understands. It’s also a mistake to assume that a child who knows how to dial 9-1-1 on a landline will know how to do the same thing on a cell phone, which requires the extra “call” or “send” button stage. Have your child practice this on a cell phone that is turned off.
2. Pre-program your child’s cell phone with all important phone numbers — including your home, your office and related cell phone numbers. Make sure that your child knows how to find these pre-programmed numbers in his or her phone and then how to place a call using a pre-programmed number. Add “ICE” (in case of emergency) to the key numbers you want responders or others to call if your child is in trouble, e.g. ICE Daddy Cell; ICE Home.
3. Tell children to remain on the line after calling 9-1-1, and to be prepared to describe their location as well as they can. While “enhanced 9-1-1″ technologies are supposed to locate wireless 9-1-1 callers automatically, sometimes they don’t work or may be off by several hundred feet.
Aylward and Sullivan also noted that the cell phone being turned on should be part of what is required when a child is away from your home. Test this from time to time. Do not accept the excuse from your child that a cell phone was turned off when you tried to reach him or her. Buy a spare charger for your child’s phone and put the charger in his or her backpack. Make sure that your child understands the need to keep the cell phone charged and turned on when he or she is away from the house.
Aylward and Sullivan said that parents who teach their children how to use cell phones responsibly in emergency situations may be able to avoid the public humiliation and even prosecution that can result from “prank” 9-1-1 calls placed on cell phones by youths. In one case currently under investigation in Salt Lake City, a 14-year-old was arrested after placing more than 1,500 bogus wireless 9-1-1 calls from cell phones.
Similar incidents involving preteens and teens abusing wireless phones have been reported in the last 18 months in Tennessee, Illinois, Arkansas, Idaho and Wisconsin. Children should understand that prank 9-1-1 calls tie up crucial police, fire and EMT resources and, therefore, are anything but “harmless.”
Though research would need to be done to reach firm conclusions, it also is possible that teaching preteens responsible cell phone use in emergency situations will make them less likely to engage in irresponsible phone use at a later age resulting in high bills for texting, excessive minutes use and other practices.
Even though children may primarily be interested in cell phones as a way to text, download music and play games, the use of an inexpensive prepaid phone can teach them to budget their available minutes – or face running out of access to phone time.
Many parents are opting to use low-cost pre-paid phones that allow them to buy their child a cell phone for as little as $15 and then use pre-purchased minutes for $20 or less for three months, versus a wireless contract plan that can cost $30-$40 a month per phone or even more.
