How Much Radiation Does Your Your Phone Emit?

Everyday, more data is released linking cell phone use to brain tumors. While none of it has been conclusive, more and more info stacks up against the mobile devices, which claim 4 billion users around the world.

While a recent study on cell phone radiation by the nonprofit Environmental Working Group (EWG) doesn't put an end to the debate, it at least provides some hard numbers that will allow the public to make its own decision. According to Wired, scientists studied radiation emissions from 1,268 cell phones, and in the end, determined "that based on current standards there's increased risk of developing brain tumors in long term users." Those words are straight from the horse's mouth, or rather scientist Olga Naidenko. The current standards, which are determined by the Federal Communications Commission, are too relaxed, Naidenko says.

Belarus Unveils Cell Phone Radiation-Proof School Uniforms

Belarus Unveils School Uniforms That Protect Against Cell Phone RadiationDespite the fact that there is hardly any conclusive evidence supporting the theory that cell phones emit brain-melting and impotence-inducing levels of radiation, there are plenty of people out there who still live in fear of their RAZRs and iPhones. For those who insist on believing that carrying a cell phone is tantamount to sticking your head in a microwave, there is hope, though; a Belarusian company has developed a special fabric that claims to protect against cell phone radiation.

Its first application will be in school uniforms that will have a special cell-phone pocket to protect students from the supposedly carcinogenic radio waves. According to Foreign Policy, the announcement of the new uniforms was made by a state official from the Ministry of Trade, implying that the government is supportive of the cellular-radiation-fear mongering.

Americans See 600% Radiation Increase Since 1980, Study Shows

Americans Receiving More Radiation, but For a Good Reason

A recent study of Americans' exposure to radiation reached a startling conclusion: On average, we're now subjected to six times the amount of radiation that we were subjected to back in 1980. On hearing this, everyone's first thoughts go to fears of cancer caused by cell phones or Wi-Fi, but now doctors and professors are saying that there's no reason to fear, because all that extra radiation is being put to good use.

For one thing, the increase is almost entirely due to the increase in radiation-related procedures being performed on Americans. Despite how it may look, though, the increase isn't due to radiation's becoming more pervasive so much as it's due to radiation treatments' becoming more intense. Averaging those figures out over every American causes misleading results. Cynthia McCollough, a radiological physics professor at the Mayo Clinic , told Live Science:
Adding up all the doses and then spreading out the total over the entire population, no matter a person's age, occupation, location, or health status is not appropriate for assessing risk to the general population.
CT scans, which take multiple X-Ray images to form a 3-D picture inside the body, are being used more frequently, but are actually far more efficient than before, and are still only being used on those who are at high risk. In other words, while there's more radiation being dealt out, most people are not seeing an appreciably higher amount of radiation, themselves, which means that we've got to put our dreams of radioactive super-powers back on the shelf.

Researchers Developing Cell Phone Radiation Detectors



As folks have become increasingly concerned with the threat of chemical terrorism, research teams are rushing to develop radiation detectors that are as reliable, compact and inexpensive as possible. Newsweek reports that one group of Purdue University researchers may very well be at the vanguard of these developments, offering inexpensive radiation detectors that fit discreetly inside cell phones.

Known collectively as Distributed Nuclear Detection by Ubiquitous Cell Phone (catchy, isn't it?), these researchers have designed a computer chip that can detect radiation and -- through its host phone's cell transmitter -- communicate with other similarly equipped phones in order to closely approximate the radiation's location.

At present, lobbyists for the Purdue group are pushing for a federal mandate that would require all cell phone users and providers to implement the chips. As there are other groups developing similar technology (and although we find this proposal to be pretty 'Blade Runner'-esque), the Department of Homeland Security has promised to support the best candidate.

Our question is this: If cell phones come to detect harmful radiation, could it be that they'll just wind up detecting themselves? [From: Newsweek]

Popcorn Popping Cell Phone Clip Outed as Advertisement

Remember the popcorn video clip we posted earlier this week, in which a trio of cellphones arranged in a circle supposedly caused a handful of kernels to pop? We knew the vids were fake, and speculated that they were part of some sort of marketing scheme. Now we have confirmation: The clips are indeed part of a viral advertising campaign, put together by a company called Cardo Systems, which markets a Bluetooth headset designed to "reduce power output by up to 99 percent."

So, no real surprise there, nor is there any surprise that these videos have spawned a series of knockoffs and parodies. Our favorite is above, which shows an iPhone surrounded by kernels that cause the iPhone itself to pop! Still fake, but funny at least. [Source: The Underwire]

Injectable Tumor Probe Tracks Cancer Treatments

Injectable Tumor Probe Tracks Cancer TreatmentsRadiation, in strong enough doses, is deadly. A short exposure can certainly kill, but controlled exposures can be useful, targeting cancer cells and helping patients to fight their disease and recover. However, the administration of radiation for cancer treatment has always been a bit of a black art, with doctors having to wait for days, weeks, or months after a treatment to check on whether a tumor has been affected. Now, a new radiation-detecting probe can let doctors know exactly how much that tumor has been affected, and can do so instantly.

The probe can be inserted directly into the tumor and report the exact dose of radiation received. From that information, doctors can calculate just how much radiation they need to apply to the patient and can more specifically target the dose, thereby decreasing the debilitating side-effects so common with cancer treatment. The probe is also RFID-enabled, meaning it can be identified and read wirelessly (in the same way that RFID technology wirelessly charges drivers with tolls when they pass through toll booths).

Right now the prototype probe is about the size of a pin -- long and narrow -- but future versions are expected to be shrunk to the size of a grain of rice. Trials are expected to begin in 2010 and, if all goes well, could usher in a new era of precision cancer treatments -- which could come in handy if all the doom and gloom about cell phone-induced cancer turns out to be true!

Scientists Create Tumor-Tracking Implant

Scientists Create Tumor Tracking ImplantScientists at Purdue University have created a device -- no larger than a needle -- that can locate tumors and detect radiation levels in chemotherapy patients.

The small RFID (Radio Frequency Identification) chip is sealed hermetically in glass and powered by placing electrical coils next to the patient. When powered up, the device can send the exact dosage of radiation being received by the tumor along with the location of the tumor. This makes treatment more efficient and less dangerous to surrounding tissue and organs.

Scientists hope to enter clinical trials in 2010 with a version smaller than a grain of rice.

Are Wi-Fi Laptops Dangerous for Kids?

Wi-Fi Laptops: A Danger for Kids?
Dr. Lawrie Challis, of the U.K.'s Mobile Telecommunications Health Research Program, is cautioning parents to keep laptops off of kiddie laps. Though he admits there's no direct evidence that children are getting ill from resting a laptop right where its name suggests you rest it, Challis warns that the jury is still out on whether or not Wi-Fi radiation (comparable to the amount emitted from a cell phone) is dangerous to children or adults. If we're already discouraging our kids from using cell phones for health reasons, he says, why not Wi-Fi as well?

Wi-Fi radiation isn't the only reason to keep a notebook computer off of your most sensitive of areas, though. Last summer, a massive recall of defective Sony laptop batteries began after six reports of them smoking and even catching fire. Researchers also believe warm laptops can raise scrotal temperature in men, which could possibly lead to fertility problems.

Scary stuff for anyone who doesn't own a pair flame-retardant, lead-lined Fruit of the Looms...
