Can we have monitors radiation free?

Question

moitors of computers are not free of radiations.radations are not good for health.it is desireous that the monitors should be radiation free,because people now have to sit before the computers for hours.this is one of the reasons of stress among it/computer professionals.

Answer 1

I am with you there. I agree with cirric, too. One can use an LCD instead of a CRT monitor. If you’re using a CRT, putting a glass filter can lessen the glare and radiation effects. Another tip is to have a good distance away from the monitor.

Answer 2

And you basis of this claim is?

First, what do you mean by radiation? Light is a form of radiation, so all monitors produce radiation. Is light harmful? Not at the levels a monitor produces.

All monitors produce heat. that is radiation too. Unless it is getting over 80 C then it is not harmful.

All monitors produce some EMI radiation - 30 MHz to 2 GHz. There is probably a lot more coming from your cell phone, your cordless phone, the WiFi in your computer. There is probably more coming out of the circuits in your radio.

CRTs do produce a couple of bands that LCDs do not.

They produce near field EM radiation in the 20 Hz to 2 kHz range. There have been lots of studies as to if this could effect a developing fetus. they have been inconclusive. despite the lack of any evidence of a problem back in the early 90's nearly all monitors conformed to the MPR II standard that massively reduced these emissions. Most quality monitors go beyond that and conform to the TCO (Swedish office worker's union) standard. You can actually get more radiation of the power cord than the monitor.

CRTs also produce some gamma rays. Normally this is at about background level, and way below the level you get from wearing a watch with a luminous dial. It can increase if there is a fault in the monitor, but all monitors are required to have a circuit that detects a potential failure and shuts down the monitor before it does anything bad.


As you might guess I have quite a bit of experience on this, so I am very interested in learning what you base your claim.

Answer 3

The amount of radiation that emits from a screen is rather low dosage. You could have radiation exposure from xrays whether medical or dental. Those are likely much higher dosage than what you are exposed to on the computer. IF you are concerned still on this, then limit your computer use to brief times when it is on. They say radiation emits from a cell phone when it's on also. It is not proven nor avoidable if this exists when you use one. There are no known reported case of radiation poisoning or overexposure on the computer yet and this has been out for several years and in frequent use by many. Use with caution in you are unsure of the safety in this just. Don't sit by it for hours to be better safe than sorry in using this.

Answer 4

anything that gives off light, is radiation. radiation by itself isnt that bad is limited and low doses. a TV or LCD dont equal a x-ray. but to my knowledge, LCDs give off light, so i dont see why some people are saying they dont radiate.

Answer 5

the older computer monitors had lots of radiation and there is a shield to protect you available

Answer 6

what kind of radiation are you concerned with? light , heat and xrays are all forms of radiation, but, not all forms of radiation are dangerous

Answer 7

Hi. Only CRT monitors emit any radiation. LCDs do not.

Answer 8

Go Flat panel LCD...no Radiation from them.

Answer 9

I thought that was only with the old, big screens. LCD screens are perfectly save and don't flicker, so they also don't hurt your eyes that much.
