The metal casing of the iPhone actually prevents the type of damage you're talking about. The plastic Android shiat doesn't offer any such protection. (not to mention being an inferior phone)

It has to do with antenna orientation.  The strongest broadcast is perpendicular to the antenna, so when you hold the fob upright instead of pointing it at the car, you are getting the maximum distance.  It has nothing to do with your head.

I'm not a cell signal nutter or anything, but I also don't think we have a very long baseline for their effects. After all, it took 50 years to figure out CFCs and DDT. Maybe it's nothing, but...I'll be morbidly curious to see the brain cancer rates for millennials in 30-40 years.

Doesn't stop me from using one though...

In concentrated-ish doses? In close promiximity to the brain case? For extended daily exposure?

No.

Higher doesn't give longer range, higher gets more crap out of the way that could otherwise absorb, reflect, or refract the photons.  Same range, less obstruction.

Not quite.  I believe they covered that the fob doesn't work from any orientation from the range he was at.  You are right in that it has nothing to do with your head, and everything to do with water reacting sympathetically to an electromagnetic field.

What physical mechanism would be responsible? Ionization is impossible with RF. DNA is too tiny to resonate at cell phone or key fob frequencies. Even if there were parts of the brain that did, it would only result in some heating. Maybe, if you want to make a case for it, inductive coupling (and man, I am really stretching here since your brain is a big soggy piece of meat as far as RF is concerned).

The only physical action would be incredibly tiny amount of heating; in which case a hat would do more damage.
 
2014-04-28 07:41:08 AM
The effects of microwaves on meat has been solid enough to spawn the rise of the microwave oven. Even though microwave ovens use frequencies higher than cellphones, it's not by very much.

The science is worrying enough that most cellphone manufacturers actually have warnings in the manuals about keeping them in your pocket close to your body, or holding them close to your head for a long time.

As we currently understand it, yes. I entirely agree.

Like I said, I'm not paranoid about it. But unlike a microwave oven, cellphones broadcast a signal. There IS a small amount being sent, which is more than humans have ever known before. We currently think it has zero effect. Will this continue? Maybe. Probably.

But we don't have much of a baseline. TV antennae did us no percetible harm, and it's likely cell phones won't either. But I will wait 30-50 years before considering that book to be closed for good.

Microwaves do not obey the laws of gravity.

You must be using your spirit energy to extend the range.

Fair enough. But my bet is you'll see nothing.

Also keep in mind that high power RF has been around a long, long time. Ham radio guys absorb way more energy than you'll ever manage with a cellphone. And the only thing they're dropping dead of, sadly, is old age.

https://en.wikipedia.org/wiki/Absorption_(electromagnetic_radiation )

The microwave oven is tuned to the same frequency that H2O molecules vibrate at. If you go high or lower on the frequency, the energy either reflects off or passes through without imparting energy to the molecule. This works with all molecules (and atoms) and frequencies. The ones that are used for cell phones are chosen because they are not absorbed by the human body and they pass through most obstacles (like walls and trees) pretty well.

Radio isn't some dark sorcery, it's just taking advantage of sympathetic vibrations at high frequencies. It has been around for over a hundred years as a functional technology.

Oh, FFS come on...I know how radio works. I know that it is most likely a safe and benign technology, and that humans have been exposed to radio waves since forever. 

But once upon a time, smoking was perceived as being  good for your lungs. Doctors prescribed it. People drank pure mercury to 'cure' syphillis, and marijuana was supposed to drive you craaaazy. 

Science advances, and understandings change. And it's in no way outside the realm of possibility that holding a transmitter/receiver to the side of your head for potentially hours each day might have an effect on you that we have no yet recognized. 

Egoy3k: Concentrated? Extended daily exposure?


Yep. And you will note, people get cancer from it and die all the time. Radiation is lethal stuff.

From the ultra-violet radiation though, which is on the opposite side of the spectrum from microwave and radio. If cellphones were blasting us with UV I'd be concerned, otherwise I think it's a non-issue.

One of the presenters on SGU tried this out a few weeks ago. Obviously not a rigorous scientific study, with counting off paces, but it's at least a start.

A certain distance from the car holding the fob at a normal height, it stopped working. Raising it to his head meant he could walk further from the car before it stopped working. Standing on a step ladder meant he could go further away again before it stopped working, so it sounds like height is the deciding factor. At least from this one attempt.

Cat psychology. It's the warm box she likes. Cats crave warmth, and love small, elevated, boxes. Put a cardboard box out with a warm towel and she'll probably go there instead.

Also, who the fark let's the cat sleep in the microwave anyway? Everything would be covered with cat hair and taste like cat.

J. Frank Parnell: The effects of microwaves on meat has been solid enough to spawn the rise of the microwave oven. Even though microwave ovens use frequencies higher than cellphones, it's not by very much.


Microwave ovens blast hundreds of Watts into the food for minutes, in a small space with reflective walls. These days cellphones very rarely send with full power, and even then only for fractions of a second, then they dial it down to just the levels necessary to ensure connection. And only a fraction of that radiation hits you.
It's like being afraid of a glass of water just because you could drown in a lake.

Yeah. It has been a long time since I learned this in college, but handheld phones were limited to 1 watt of transmitting power (or something). Comparing that to a 1000 watt microwave doesn't seem very productive.

I've been doing this since I learned of it in 1997, which was also my first RF keyfob. A little different though, as I learned it as pointing the fob upwards into my chin. Myself and six other engineering students put the technique through its paces, and it very clearly extends the range, and doesn't at the same height with just air surrounding it. No debate.

One other unrelated lasting tip I learned that year: after you shave with a blade, tap the blade on your towel to get most of the moisture off of it, then put a drop of mineral oil or baby oil on the blade and let gravity pull it across so the entire edge of each blade gets a visit from the drop of oil. This will evacuate the water from the edge, so it won't evaporate there, leaving behind minerals that disrupt the sharpness of the blade. My Gillette Mach 3 blades now last me about 6 months each. I haven't bought a new pack of blades in 4 years. The lubricating strip comes off after a couple weeks, but that's not needed for a good shave. This is an effective demonstration that the stainless steel blade is not deforming (dulling) by cutting hairs -- it just appears to dull because it gets covered with minerals. I imagine that a rinse in distilled water would produce similar results...
