Hello, i happen to live very closse to a mobile phone base antenna (20-25meters from it) and recently, i found this (quite expensive) paint ,that once applied in a room it keeps out electromagnetic waves...
Does any of you have any knowledge on the subject??? Does this paint actually worth my 500$ for 5 liters???
Thanx in advance !!

Send that cell phone company a bill for it. If they pay the bill, buy your paint. Or just buy weed with the money.

from my research, a faraday cage is the only way to cancel out em fields
check it out on wikipedia.
i would most likely think that the paint is a scam.

Do mean magnetic flux? Electromagnetic waves included everything from microwaves, radiowaves, light, ultra violet, x-rays, etc.
Black paint would keep out electromagnetic radiation in the 400 - 800 nm range. What kind of electromagnetic radiation are you trying to keep out? It's just going to depend on the wavelength of radiation you want to keep out.
I'm just curious, by why the fuck are you afraid of electromagnetic radiation below the visible range in frequency? Have you been reading jiberwoky about radiowaves causing cancer?
If, on the other hand, you're talking about magnetic flux (that is, magnetic field lines), then the only thing I've heard of that does that is a superconductor. Superconductors don't do that until they are below their critical temperature, which is generally below 120 K (-153 C, yes -153 Celsius). Unless you're painting a superconductor on your bedroom walls and pouring liquid helium on your walls constantly, then I don't see this paint doing anything.
If this is what you're afraid of, then why are you afraid of magnetism?

From the context of his question Im think he wants to shield from the antenna he lives next too.
I think cell phones use microwaves, with a wavelength around 35cm (or frequency around a 800 MHz).
Look up what waves, specifically, are being emitted. Then look for something that can attenuate (block) them the most.

Why do you want to shield a room?

I have a friend who has a huge powerline tower thing in the back of her yard. I once saw her husband hold a long fluorescent bulb about 10 ft from the tower and it started to light up.
She has lead sheeting lining her attic.
I'd be interested to hear if this paint works. Maybe there's lead powder mixed in with the paint? Yummy

Lead has no effect on the kind of radiation coming from power lines. Not that it matters judging by the studies I'm aware of. I don't think any conclusive link to health effects from power lines has ever been discovered. Same for cell phones. Painting and lining walls with lead seems like paranoia to me.
Besides, radiation is all around us all the time, whether we like it or not. Every electric device produces EM radiation. Your hair dryer produces a localized EM field FAR stronger than anything a power line produces in your home. When you drive your car, you're surrounded by a FAR stronger EM field than anything a power line would ever produce in your home. Even the ordinary wiring in your walls is producing EM radiation. The only way to avoid this is to live in a cave.
Cell phone towers are engineered according to FCC regulations that do not allow them to be placed too close to people. The intensity of EM radiation from a cell phone tower drops off asymptotically, so beyond a certain distance, the radiation is so weak that it's lost below the noise floor of natural environmental radiation and other sources of EM.
Even ionizing radiation in low doses is all around us all the time. I heard on NPR this morning that if you eat a banana, you'll radiate yourself a few millirems from the radioactive isotope of potassium in the banana. This is completely natural.
Even your own body emits ionizing radiation from radioisotopes you consume in ordinary life. Your significant other's body radiates you when you're close. Your body radiates your kids when you hug them, as they radiate you. And radiation from space rains down on us 24x7.
Given the giant web of power lines and cell phones all over the world, if there were real health risks, hard epidemiological evidence would have been found by now.
Worry about REAL threats to your health, like smoking, fatty foods, and being overweight, not power lines and cell phones.

+ the lead you line your roof with/paint on your walls, which has proven negative effects...lmao

actually i have heard that living around powerlines is dangerous, but not for the above listed reason.
From what i understand, the high power levels directly around the power lines can ionise particles that are in the air. This makes them more likely to attach to lung and skin tissue than non ionised particles.
