Cell phone brain cancer!! ionizing vs. non-ionizing radiation

[GoodEnough]

What do you tell people when they raise this issue?

Radiation released by nuclear bombs is obviously harmful. Known as ionizing radiation, it is powerful enough to remove electrons from atoms. By contrast, radio-frequency energy is a form of non-ionizing radiation given off by cellular and portable phones, Wi-Fi routers, baby monitors and countless other devices.

[Matthiasa]

In high enough quantities non-ionizing radiation can be harmful, or those in near ionizing range. Cell phones are neither but those that are bad with data/science will continue to believe things that are not true so there is little that can be done to help them.

Yea but it could likely denature proteins.

Yea but it could likely denature proteins.

By what mechanism? The heating caused by cellphone radiation would be minuscule to non-existent based on the amount of energy a cellphone puts out.

On the topic of radio waves: we frequently use radio-frequency pulses to study proteins inside of a magnetic field, as they provide a low-energy and non-destructive way to study protein structure and dynamics (see: nuclear magnetic resonance spectroscopy).

I'm more concerned with the spyware

 

[DrPizza]

I tell people that Einstein got the Nobel Prize for proving that cell phones can't cause cancer - decades before cell phones were even invented. Then, I tell them that making false claims sells a lot of books and makes money for dishonest people who take advantage of ignorant people.

Like in-vivo as its undergoing a conformational change as it does its work or...?

🙂

A fever can denature proteins. Why do you think a 107F fever is fatal. It specifically seems the brain is most vulnerable to high temperature.

I'm more worried about the idiot texting on one when I'm driving down the road.

Show me a cell phone that can raise your brain temperature to 107 degrees.

Everyone uses Bluetooth these days.
Seems like a non issue.

But you gotta sell your snake oil somehow

 

[BarkingGhostar]

Addicts seldom care about the harm being potential done to them by their subject addiction. So why discuss? You want your cake and the ability to eat it, too, without the need to manage the calories.

Nothing that can change their minds.

Any evidence presented against the idea is just part of the conspiracy to keep the danger quiet.

It's probably fine, I have a cell phone and Wifi stuff... but I'm still not going to hang out for hours right beside Wifi routers or home phone base stations.

They use microwaves for an mri, right? It changes the spin of hydrogen electrons or something and they watch to see how long it takes for them to realign with the field? I would guess that those microwaves are a lot stronger than the emf from a cell phone though.

But yeah, anti-vaxer, doctor oz, snake oil is pretty pervasive.

 

[Matthiasa]

An MRI uses magnetic fields, not microwaves, hence its name. (magnetic resonance imaging)

Noting they do use lower frequency waves to generate the magnetic fields.

Sorry. The radio frequency used is more in the shortwave band than microwave band. And it's the hydrogen protons not electrons.

MRI and NMR both use radio waves. Applying a radio-pulse changes the difference between up spin and down spin state in nuclei and then you observe it as it returns to equilibrium.

There are some pretty cool things in NMR that use microwaves, like dynamic nuclear polarization, but that's not widespread and has all sorts of technical hurdles.

The spectroscopic technique that primarily uses microwaves is EPR (electron paramagnetic resonance). That is the one that applies microwaves to observe spin state changes in unpaired electrons. Usually people add a paramagnetic spin label, which has an unpaired electron, to their sample of interest so that they can actually use EPR (most things don't have unpaired electrons).

 

[rh71]

We've been exposed to all these electronics since maybe around 2000. Has there been an increase in cancer rates?

Ask the 911 first responders about cancer rate deaths that have already happened.

Tell them their brain cancer is making them stupid.

Briefly, MRI and NMR use a large, static magnetic field, usually created with a large, cryogenically cooled electromagnet. Then, it uses radio waves sent through a probe (which contains the sample) in the magnet to create other, weaker magnetic fields to probe whatever system they are studying. This works because light has both an electric field and magnetic field component, however, only the magnetic field from the radio pulses is perturbing the system. Usually, people try to design probe coils such that the electric field isn't going to be going through the sample, since that can cause heating if the frequency is high enough and pulses are on long enough.

(Biological NMR is the field I currently work in).

So does the RF coil go all the way around the hole (for human mri's) or is it more like an antenna?

The thing I don't like about them is the contrast agent. You're not supposed to be able to metabolize the molecule that contains the gadolinium but the agents currently in use (linear agents?) do get partially metabolized as evidenced by bright spots in the mri's of people who get them frequently. Personally, I'm trying to avoid any mri's until they start using cyclic agents which tend to not be metabolized.

The RF coil in MRI is usually the device they put on you. It's smaller than the bore of the magnet. Coils don't have to be solenoids that wrap completely around the person or sample.

Stick...

stick your brain in it.

Preferably really long periods of time.

Then get back to us.
