Cell phone radiation

[john70t]

I knew someone lost to jaw cancer. Perhaps other factors were involved but he did not smoke and seemed otherwise very healthy until I heard the news. Sometimes my jaw starts to feel warm while talking with people and I'll hold the phone away. Also good for people who talk too much. Direct skin-contact makes the radiation transfer much worse.

Anyways the differences in levels seem quite astounding.

This is radio waves, right, not nuclear radiation.

[john70t]

Yes. Right there next to microwaves.

Not to worry...

"Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (e.g., the ear and head). However, it is not sufficient to measurably increase body temperature. There are no other clearly established effects on the human body from radiofrequency radiation."

I thought this was going to be a 5g thread.

Continue circle jerk

Would it not cause cancer to the hand ? The phone is not really touching the face but is directly in contact with the hand.

In amateur radio, the power output is much much higher. Handi-talkies can be up to 5 Watts. I remember the biggest concern was a wavelength which matched the optic nerve, about 3-6 cm. Most HT's are 2m/60cm.

I think most of the cell phones these days max-out around 300mW. And most of the time they run far lower output.

As far as "heating" is concerned, the reason microwave ovens use the specific frequencies they do is that they are readily absorbed by water. And 1200 WATTS takes a minute to boil a 8 oz (250ml) of water.

Assuming 10% of a 300mW signal were absorbed, that is 30mW. (I say 10%, because if 100% of the signal were absorbed, the call would drop.) 30mW can hardly cause any heating.

No.

The energies at these wavelengths are not sufficient to knock electrons loose from DNA molecules, much less protons or neutrons. Alterations in DNA are what 'causes cancer.'

Cosmic rays & X-rays have MUCH shorter wavelengths and thus higher energies. They do cause cancer.

I don't think you can take a single event and draw conclusions from it. As others explained, there is no mechanism that would make sense to cause any mutations and I bet we would have picked up on increase in cancer rates if this was a concern. Remember, people were afraid of the speed in railroads, food out of the electric oven and microwaves ...

There are proven areas to reduce cancer risk, including mouth / throat. HPV vaccination for example. Both men and women. But the anti-vaccers are usually also the anti radio-frequency crowd. So there is that ...

Yep, and the same folks that claim the smart electric meters are causing them discomfort.

I used to work with a chick that heard someone say they were going to "nuke" their coffee to warm it up in the office microwave. She was convinced that it was going to be radioactive. I tried to explain the microwave radiation in nothing like nuclear radiation. There is no block or uranium in the microwave oven. She was never convinced, but she was dumber than a brick, and fired for incompetence shortly afterwards.

My guess is that the heat is caused more by the contact and maybe the battery warming the phone which then warms the face due to direct contact. I don't think any radio frequency radiation from phones is going to have any measurable affect.

Cancer has been around for a long time. Lots of folks get cancer in lots of places. I suspect people have been getting bone cancer in their jaw for a long time, and that it had nothing to do with cell phones and wasn't necessarily linked to tobacco either.

A friend of mine died recently from Lung Cancer. He was a devout Mormon. Never had caffeine or smoked a day in his life.

My sister got rid of her first microwave oven (which my parents paid something like $800 around 1978) because of fears of "radiation". She will believe anything from anyone but a direct family member.

That is quite a reasonable other explanation.

There are people who are more sensitive to certain effects. (and yes there are also hypochondriacs)

In humans, as a child I could hear the radio tube tv downstairs as a sharp whine but barely the sound. I lived in an apartment which a transformer pole outside and would get splitting headaches. Energy is now readily transformed between states but still exists. Things we can not see and hear can also be used as weapons: https://www.theguardian.com/world/2017/sep/14/mystery-of-sonic-weapon-attacks-at-us-embassy-in-cuba-deepens

I once received acupuncture from an elderly Japanese master who was a medic in the war. He could feel the heat which builds up from injured areas of the body. This stranger was accurately diagnosed by him in about a minute.

Obviously birds etc navigate the world using only the magnet(radar) in their tiny beaks. Whales communicate across oceans using only the hint of subsonic frequency. Higher levels. Lower levels. Whatever. Humans have lost most of our keen senses in our modern overloaded world, which once let us smell and hear for miles and kept us alive. Let's not rule out that these are probably around but latent.

birds navigate the world using only the magnetite particles near their beaks but processed in the brain

Google Walt Wiltschko for more

it has nothing to do with radar or cancer

[gordner]

Birds navigate by essentially a natural compass with absolutely no similarity to radar systems.

Webb, I believe that is still theory.

It is highly possible and may be correct but their is no absolute proof at this time.
