why is everyone suddenly concerned with cell phone "radiation"?

why is everyone suddenly concerned with cell phone "radiation"?

I thought I knew more than this about electromagnetic radiation… I even had to educate my 8th grade teacher on the thought that higher energy output means lower frequency (he marked it incorrect)…

Now I’m 21 being ancient and I never stopped learning and I thought I had this thing unwritten… cell phones use microwave radiation, the same kind emitted in kilowatt levels in radio towers everywhere technicians climb up to make maintenance/repairs, and the same kind that has never been conclusively shown to do any hurt at any level…

and why the constant use of the term “radiation”??? this term evokes images of gamma rays and x-rays, the ones that are really harmful. When you really get down to it, though, even visible set alight can be called radiation, and nobody is issuing consumer reports about set alight bulbs, not even the new florescent set alight bulbs that emit a lot of UV set alight, and UV set alight HAS been linked to cancer…

So long question small… what am I gone here? Do cell phones have some source of uranium that I am unaware of?
OK, correction, microwave radiation can boil you inside out at a high enough level, but it has never been linked to long term hurt.

It’s called radiation because it is radiation. There’s no point in calling it anything else.

Cell phone radiation is harmless. It has less energy per photon than visible set alight, so it is even less liable to ionize atoms than visible set alight would be. It is this ionization which scrambles DNA and causes cancer.

From buck to highest energy per photon, here is how humans arbitrarily divide the electromagnetic spectrum:
Radio – Microwave – Infrared – Visible – Ultraviolet – X-rays – Gamma rays

Only the upper ranges of UV and beyond (X-rays, gamma rays) have enough energy to ionize atoms. Therefore, only those frequencies can produce cancer.

As for why it’s constantly called “radiation”…uh, what the other guy said. That is *technically* what it is.

It’s not really a “sudden” obsession – cell phones have been widely used for over ten being, and people were concerned from the beginning, especially considering those ancient brick-style phones were analog, not digital, and so place out a larger signal (at least, when comparing just phone calls – new phones also are web enabled, and are often Tx’ing & Rx’ing larger amounts of data).

At first, yes, it does seem silly for a lot to be made over these signals. I did hear recently that a study of lab rats exposed to high levels of “cell-phone radiation” showed no harmful effects at all, and only one effect in total – an apparent increase in brain function (!). But there have been other studies on rats that have linked moderate cell phone use to *decreases* in cognitive abilities. We *do* use our cell phones next to our *heads*, after all, and it’s hard to replace one’s brain when there’s a foot-sized tumor in it. (We don’t place set alight bulbs up to our heads – least, *I* don’t, dunno about *you*….)

As for microwave radiation not doing any hurt, I reckon that Turkey Hot Pocket you singed last week would disagree….heh, heh. Yes, microwave photons may have less energy than UV set alight, but UV set alight stops at your skin…microwaves can travel through your body!

I also remember a study done in Norway (one of the countries with the highest rates of cell phone use over the past 10 being) which seemed to indicate a correlation between usage and the incidence of brain tumors.

There have always been debates about EMFs, going back to the ’70s and ’80s, especially revolving around those HT shape that carry 500,000+ volts. So, I rather doubt that the arguments will disappear completely for at least a couple of decades, in anticipation of more studies can be done, and solid conclusions can be reached. Even as of now, there is simply not enough data on the subject, whatever one thinks of the likelihood of ionizing radiation coming from your cell phone, to make out the case that cell phones and their signals are absolutely harmless. Remember, it was only in the 1960s that a correlation between smoking and heart disease (much less lung cancer) was learned – before that, even doctors smoked!

Sorry for my long answer. Just tryin’ to be thorough.

P.S. um, I did mention that there *have* been studies that linked long-term exposure to cell-signal radiation to increased risk of certain cancers….

Answer by jake z
you dont need radioactive material.
visible set alight is em radiation
so is your radio waves
so is x rays and gamma rays which are harmful
i dont know the wave length of cell phone is strictly in the radio region
even in that case all cell phones have to clear a absorption test and should be less than some figure. why are they doing this ? because there may be some effect.
possibly it is because it is very close to your head while you speak
you should not fall into the intelligence trap of being arrogant and neglect any more input because you are so sure of your fundamentals. listen with a more open mnd. so many researchers are conducting studies all over the world to test the radiation effects. there has to be a reason for this.
everyone laughed at einstein said set alight was made of particles and when he started relativity.

all the best

Lars P. Reichelt, CEO of Cell C
consumer reports on cell phones

Image by Axel Bührmann
On its ninth birthday, Cell C reports that it has switched on its HSPA+ 900/2100 network in Johannesburg and Pretoria.

The company claims that its launch in the economic hub of the African continent brings both "world-class" speed and pricing, and says consumers will be looking at paying from R0.03c per MB for data at average download speeds of between 4 to 7 Mbps and average upload speeds of between 2 to 3 Mbps.

"Johannesburg and Pretoria are trying to take in and we needed to make sure that our network was tried and tested and ready for our customers before we pushed the button," said Lars Reichelt, CEO of Cell C.

He states that since the company started rolling out its new network crosswise the country, it has been "inundated with queries from Gauteng residents, wanting to know when we would be going live in this part of the country"

With the launch of its HSPA+ 900/2100 network, Cell C provides what Reichelt calls "speedcover", adding that "the days of slow, unreliable and expensive internet are officially over."

Cell C's new network will initially take in 62 percent of the population in the greater Johannesburg and Pretoria region, with 89 percent population coverage of the area plotted by the end of January 2011.

At the same time as its Johannesburg and Tshwane launch, Cell C says it has also officially opened its new HSPA+ network nationally for all unfilled Cell C customers.

"Cell C customers that have UMTS 900 competent mobile phones or USB data sticks can now use Cell C's superfast data tie and will experience much better voice call quality," clarified Reichelt.

I have terrible credit but always pay my Verizon cell phone bill on time. I have 2+ being with them now. Is there a credit reporting serice that reports these kinds of bills on time to the credit bureaus? I have found one called PBRC (link is below) but I want to know of a service that will do this in the future or if PBRC will be worth looking into. I looked on there site and i dont know how much it would cost besides $ 20 verification for each account. Thanks! I am looking into Suze Orman’s FICO kit by the way for $ 50. Is it worth it? I am out of debt by the way. NOT IN DEBT!

I already have chose to go with Bank Of America secured credit card. $ 300 down and will charge $ 90 or less a month which is 30% or less of my limit. It reports to all 3 CB’s but as secured. I need to find out both MyFico scores from TU and EX thats why I want the FICO kit and it has a simulator.

Answer by Judy
This PBRC, could very well be a scam.
There is absolutely no way to get utility bills, cell phone bills, or renting furiture to report to the credit bureaus.
The only way PBRC could possibly make money is by making you a seriously high interest loan, and reporting your repayments to the credit bureaus.
But… most liable they will only charge you a processing fee and then turn you down for insufficient credit.

Before doing business with any company google the name of the company followed by:
complaint, scam, rip-off.
There is a rip-off somewhere with this company.
If you dont’ see anything, it could be a company that just got a new name, because the ancient one closed down due to scam.
My point – all companies have complaints – there will be someone on it online.

Simply go to your bank, question for a secured credit card.
Bank of america has them if your bank doesn’t.
A secured card turns into a credit card in as small as 6 months with excellent usage.
Use it unwisely – not pay in full for what you use each month, and it could take being.
Google secured credit cards – go with a local bank – not an internet bank for this.

Rent and utilities are not considered extensions of credit and are not reported to the credit bureaus unless you default and the account is sent to collections.

PRBC is a complete waste of money. They claim to be another credit chest of drawers. But they charge you to list your bills. They may very well maintain a data base of your payment description. Though, creditors use Experian, TransUnion, or Equifax, not PRBC.

I haven’t looked at what Orman’s kit includes but I doubt it’s worth $ 50. The MyFico site has lots of excellent free info on how scores are figured. But if you want to build a credit description, you need credit cards or installment loans that report to the huge 3 credit bureaus.

Consider getting a secured credit card — you pay a deposit which is held as collateral against your line of credit. Use the card for small buys and pay in full each month. In about a year, you should be able to convert the secured card to a regular account and will have some credit description.

Answer by William
Stay away from PBRC – it’s a scam. Utility and phone bills are not “credit” and do not report to credit bureaus (unless you default). “Credit” means BORROWING money and repaying it. Try starting with a secured credit card.
