Renagade 0 Posted October 24, 2002 Why! and what health risks too ?? Th reason being is that i was messing aound with my radio awhile ago and noticed that sticking it near the pc or any of its peripherals like th mouse & trackball caused it to go into static overdrive. Now compared to console pads like the ps2 pad which not only has duel analogue sticks but all its buttons are analogue too yet causes less static than a 2 button mouse which means either the ps2 pad emits less radiation or its of a different 'frequency' so it doesnt give the same effect and then theres the other crap off the monitor ......... I was wondering why and also what hazards are there.I`ve read some articles claiming that the electromagnetic radiation given off is related to RSI and some other articles claiming its perfectly safe and some garbled results spewed from search engines too. It was kind of bugging me so i thought id post it here Share this post Link to post Share on other sites
Frisbee 0 Posted October 24, 2002 All that radiation stuff is pretty much BS imho... If you'd constantly use a cell phone against your ears,constantly calling that would be bad,but every electronic device emits radiation,tv's,console's,discmans... Share this post Link to post Share on other sites
Renagade 0 Posted October 24, 2002 True,but some are of a different nature and power levels and other things are shielded while others are not then again its like some of those other debates like whether putting fluride in the water supply is hazardous or amalgam fillings cause health problems due to their mercury content and so on....

red oct 2 Posted October 24, 2002 we even use radiotion to heat our food. how do you like your chicken? nuked or nuked to incineration? Share this post Link to post Share on other sites
kegetys 2 Posted October 24, 2002 If you use a regular radio to measure the radiation levels, then I think your biggest problem are the local radio stations and not your computer Share this post Link to post Share on other sites

It was kind of bugging me so i thought id post it here <span id='postcolor'> Computers generally give off a lot of RFI (Radio Frequency Interference). It's just the nature of the beast. Most computer cases are designed to block most of it. But that's only if the case is completely assembled. If you run it with the sides off, or have a big old blowhole fan in the top, or a window in one of the panels, that can degrade the ability to block RFI. This type of radiation is, to the best of my knowledge, totally harmless to people. What it does do is cause radio and television reception problems... as you've discovered. My guess is that the PS2 lacks a lot of the devices (hard drives, modems, etc) that are inside a computer, plus they are well shielded because they are devices intended to be put to televisions directly..thus any interference would be a really bad idea.

Die Alive 0 Posted October 24, 2002 I have a radio less than 30 centermeters (one foot) from my monitor, and I only get radio static when i first boot my computer and it's showing all that dos stuff and then the splash screen. When the monitor switches to SVGA, it sounds perfect. -=Die Alive=- Share this post Link to post Share on other sites
IceFire 0 Posted October 25, 2002 Hmm, I think so too. I think monitors give off radiation. That is why they are bad for your eyes. This is why I want to put one of those things that block radiation on my monitor. Share this post Link to post Share on other sites
second_draw 0 Posted October 25, 2002 you ain't gonna stop those gamma rays. why? Alpha radiation = helium 4He2 = stopped by cardboard and stuff due to such slow speed and large size Beta radiation = electrons = stopped by a centimeter or so of lead Gamma radiatiobn = complicated = stopped by not much really , if i remember correctly, 4inchs of concrete of lead will stop only 10% due to light speed velocity and etc.... what causes these radiations is the decay of an atom. Why there is any materials like this in your machine decaying is beyond me, what i think is the problem is "electro-magnetic radiation". Much better then previous radiations but still not fun. I can't exactly remember electromagnetic radiation but it mainly from high voltage power lines and stuff like that. Research says that high voltage power lines cause medical mayhem and i think if you want more then you can get it cause i a bit sleepy at the moment..

ran 0 Posted October 25, 2002 the reading of this thread gave me an headache ..... how can you , young nerdy teenagers can know so much about radiations and other physiscal stuff like that ?? Share this post Link to post Share on other sites
WhoCares 0 Posted October 25, 2002 Maybe because not everyone is just a teenage nerd, but there are also some electrical engineer nerds EMI (electro-magnetic interference) has different faces: 1. EME (electro-magnetic emission): an electrical devise emits too much waves, causing malfunctions in other devices. 2. EMS (e.-m. susceptibility): an electrical devise doesn't work properly in its supposed environment. Main emitters in a PC are graphic cards and CD/DVD-drives. To be within the limitations, some graphic card manufacturers use 'bad' signals (more sinus like, instead rectangle) to limit emitted radiation. There is also a safety issue, not directly related to the radiation, but to its effect on other appliances; just imagine the airbag opens when you activate your mobile in a car. Monitors are no big emitters (at least not to the front), but they are easily influenced by other devises., e.g. speakers with their big magnets inside. About the biological effects, high power, low frequency (power grids), and low power, high frequency (mostly pulsed, like DECT or Mobiles) - their were/are many studies about and the results are mostly dependent of the sponsor of these investigations Power grids are assumed to be responsible for higher cancer rates, Mobiles might influence some processes of growing up with childrens.

The EM field that surrounds your PC has a much lower energy and can be shielded easily. You can't get away from the EM field since it is induced by the current that goes through the wires. An electrical current always induces an electrical and a magnetical field. Share this post Link to post Share on other sites

A device called Gamma Ray Spectrometer would be a better choice, but as denoir pointed out, neither alpha or gamma radiation is emitted by a PC. Monitors/TVs and any cathode ray tube will however emit small quantities of beta radiation. The free electrons that simply managed not to hit the phosphor. But unless your CPU is made of a Thorium core then you shouldn't worry about your children being born as mutants. As far as interference of the monitor with the radio it's perfectly alright. When the monitor is refreshing at 60Hz any radio receiver in its close proximity will be affected. Higher monitor refresh frequencies usually work better, like my sweet 85Hz @ 1600x1200. EM radiation in most cases with house devices is far too weak to upset any cells in our body. You have a higher chance of getting them upset by sun's UV rays during the summer or spending excessive time on your cell phone. Would be pretty ironic if you got brain cancer from spending 8 hours on yoru cell talking about the possibility of getting a cancer, but the big conglomerates assure us it's perfectly safe so along we go children. They control the masses after all. Share this post Link to post Share on other sites

In the electromagnetic spectrum, the ELF frequencies (30Hz to 300Hz) and the VLF frequencies (3kHZ to 30kHz) are causing the concern. Â VDT screens also give off static electric fields, which have been indicated as the cause of skin rashes and dermatitis in VDT operators. Â <span id='postcolor'> From my understanding this is caused by the flyback transformer(CRT monitors) which give off more radiation at the back and sides of the monitor either that or its more shielded towards the front. Still doesn`t get my anywhere closer to why my mouse generates so much of the stuff when other input devices dont, same kind of question really as why do MS mice use those stupid visible infra-red LEDs to power their optical mice/trackballs when other makes like logitech use the invisible LEDs* like in ur TV remote. * invisible only to ur eye,some webcams can see the the type of light given off due to the sensor used Share this post Link to post Share on other sites

Whoever talked about getting a thingie for the monitor, you can, but you will most likely find yourself raising the brightness and compensating for the screen. On the other hand, most professional monitors these days give off almost pure light due to special filters placed infront of the phosphors. That means it's as bad as the light hitting your eyes. Important thing is for all wavelengths hitting your eyes to be in the visible range, otherwise your eyes will get tired. Share this post Link to post Share on other sites
