If you plugged a geiger counter into an infant's optic nerve, would it be able to see radiation?

Doubtful. The Geiger or whatever would probably have to supply an interface that matched the kind of innervation that the retina has.\n\nAlso, this would be fiendishly unethical.

Everything in this universe emanates radiation, including your body. The only exception is objects that are already at absolute zero.

yes. geiger's invention, the geiger counter, is inherently important in towns or areas suffering from radiation poisoning. it allows families and individuals to determine whether or not their food, clothing, and other items are safe to use. it also helps scientists in their testing by determining how much radioactivity there is in a particular substance.

The cloud chamber, also known as the Wilson chamber, is used for detecting particles of ionizing radiation. \n\nclick here:http://en.wikipedia.org/wiki/Cloud_chamber

No, you might be thinking of gamma rays.  Several things can be done using gamma ray coincidence, but only one alpha particle is emitted in alpha decay.

Irradiate it with gamma rays.

Well if we're actually taking this seriously and you're not an alien then your best chances are in the Marvel method. If you expose yourself to Gamma rays, get a genetic mutation on the DNA level or get bitten by a radioactive animal, come back and tell us all how you're getting on! :)

Its called a geiger counter.  \n\nCheck out this link\n\nhttp://en.wikipedia.org/wiki/Geiger_counter

Computers don't emit harmful rays, only a bit of RF noise.\n\nCRT monitors, on the other hand, emit a small amount of radiation. This is such a small amount that it is harmless, but if you want to avoid it then you should get an LED monitor instead.

Don't be ridiculous, radioactive stuff doesn't glow. However, Hollywood screenwriters think it does. \n\nIn some instances high-energy radioactive particles will cause other stuff to glow, but that's an exception, not the rule. On old radium watch dials the radioactivity from the radium would cause zinc sulfide to fluoresce, but you cannot see the radioactive particles themselves. Radium by itself will not "glow green" and you cannot see electrons or alpha particles unless they react with something (e.g. the phosphor screens in oscilloscopes).

It has happened and far to often.  I read a story about a young father taking his two year old son to day care on his way to work because his wife was sick and the stress of the day he forgot to drop him at the daycare and left him asleep in the back of his car when he got to work.  The baby wasn't discover be for being dead for two hours.  The daycare tried to call the mother at home but she had taken the phone off the hook so she could rest and the father's work number was not listed with the daycare center.I think your concern is well placed and I believe there could be many ways to alert the drive of a child or animal left in the car.\n\nGeneral Motors Develops Device To Prevent Heat Stroke in Car Occupants.\n\nCOPYRIGHT 2001 The Washington Times \n\nByline: Tom Ramstack \n\nApr. 27--General Motors Corp. announced yesterday it is developing a radar technology to prevent heat stroke in children and animals left in automobiles on hot days. \n\nThe radar detects the presence of people or animals by their normal movements, such as eyelids blinking, mouths moving or chests inhaling and exhaling. A second device monitors temperature inside the vehicles. \n\nWhen the temperature rises too high while children or animals are inside, the device sounds three short blasts, or "chirps," of the automobile horn. \n\n"We have many parents who are unaware how quickly a vehicle heats up," said...

Well in a sense one can. Or at least you can with a microwave telescope or a TV (I'll mention the TV below.)\n\nA microwave telescope detects a almost homogeous wall of radiation - this is left over from the Big Bang. The radiation we see in this way is from a time around a million years or so after the Big Bang. This was the first time when the universe was diffuse enough to be transparent. Light emitted before this time was absorbed.\n\nSo essentially if one looks anywhere (with a microwave telescope) you can look towards the center of the Big Bang. In that sense it is in every direction.\n\n\nAs for TVs, it turns out that if one takes an ancient YV with an antenna and puts it on a channel where there is no station, that about 1% of the static is from the background radiation. In otherwords some photon has travelled 15+ billion light years - almost since the begining of the universe - and ended up in your television.

if you dont die from the radiation i think thats pretty super, dont you? :)

use a collimator.or magnetic fields.

good grief - there is a lot of 'part' knowledge here...\n\nyou need to break this down and talk about the different parts of what the original question was asking.\n\nif it was 'see', the explanation would be the same as for hearing by the way. (it would be easier to explain about seeing)\n\nhere goes...\n\ninside your ear you have these little hairs (cillia) that are a certain distance apart. when a sound wave enters the ear the wavelength of this wave will stimulate hairs at both its high energy points (its troughs or peaks, you choose, not important) your brain knows the distance of the hairs and so can interprut this wave distance between two lots of hairs being stimulated. thats how you get the frequency (number of wavelengths in a second) of sound in your ear. the volume (loudness) depends on how vigourously the hairs are moved by the sound wave. (thats why you can go deaf listening to loud music - you kill those little hairs if too loud). \n\nnotice i said sound!\n\nyour question is about electromagnetic waves. radio waves and visible light (green) waves are both of the same stuff (light energy - some we can see and some we cannot). the organ for detecting this energy is the eye. inside the eye, the retina (back of the eye) has special cells called rods and cones for detecting different wavelengths (i believe this is what your engineer was on about). each of these cells has a specific chemical for detecting a certain wavelength. lets pick on one.\n\nthe red light cone has a protein inside that has a special part that can move to a slightly higher energy form (a more awkward position for the proten so it wants to get back to where it was before - think of bending a ruler... the more you bend it, the more it wants to get back to where it was... so the higher the energy it has) when red light is shone on that protein (inside the eye) it provides enough energy to move this extra part of the protein (called an apoprotein portion is anyone wants to know) to a higher energy state and this is enough to induce (make happen) a signal being sent to the brain that says 'red light detected' and we see red light.\n\na similar thing happens to green light.\n\nin physics, when we talk of waves whether in music or lihgth or nanometers, if you have something of the same wavelength then it is detected as the same.\n\nif you have something of a different wavelngth then it is detect as different ( or in the case of the eye.. or even the ear, not detected at all, unless your are green, red or blue light)\n\nbut if you have a wavelength that is say  x2 bigger, of x3 or x6 or x2000 times bigger exactly, with no extra and no bits needed.. it has to be exact. then these also will be detected.. A BIT. we call thesse harmonics. this is a word that belongs to music.\n\never notice the way a piano has all those notes (only 8 notes and yet so many keys..?) these eight notes are repeated but in higher registers/keys, but they are still the same note.... a higher harmonic. all these wavelenths are doubled or trippled or what ever.\n\nso, because there will be a harmonic of green light in the radiowave part of the spectrum... it can theoretically be detected. so you could theoretically detect green light (with the eye) and radiowaves (theoretically with the eye)... but never with the ear :-)\n\nhappy days - now lets look at information theory! why do we always lose information and yet still maintain the integroty of the message? at what point is the message lost?

The longer you hold a cell-phone/mobile phone to your head, the more exposure to radiation you receive.\n\nIts best to use the phone with respect, and use it no more than you need to.\n\nNo, I am not kidding you. All you have to do is use a search engine for "Cell phone radiation exposure". The younger you are the more risk. Parents should ever be holding a cell phone to an infant's head for this reason.

A ct system doesn't generate enough radiation to change the water.  And yes, it is safe to drink.  I would make kool-aid, set up a stand and safely sell it to neighborhood school children!
