All objects give off some sort of background radiation. Radiation was thought to be produced by the cathode ray tube of computer monitors, however this was only small amount of radiation and there has never been any proven evidence to show that this level of radiation is damaging.

The Cathode ray tube (CRT) is a vacuum tube containing an electron gun (a source of electrons) and a fluorescent screen, with internal or external means to accelerate and deflect the electron beam, used to create images in the form of light emitted from the fluorescent screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets and others.

CRTs can emit a small amount of X-ray radiation as a result of the electron beams bombardment of the shadow mask/aperture grille and phosphors. The amount of radiation escaping the front of the monitor is widely considered un-harmful. The Food and Drug Administration regulations in 21 C.F.R. 1020.10 are used to strictly limit, for instance, television receivers to 0.5 milliroentgens per hour (mR/h) (0.13°C/(kg°h) or 36 pA/kg) at a distance of 5 cm (2 in) from any external surface; since 2007, most CRTs have emissions that fall well below this limit.

Radiation poisoning can show a number of symptoms which should be watched for. These symptoms can be dividied into three main sections: Hematopoietic, gastrointestinal and neurological/vascular. These symptoms may or may not be preceded by a prodrome. The speed of onset of symptoms is related to radiation exposure with greater doses resulting in a shorter delay in symptom onset.

Hematopoietic syndrome is marked by a drop in blood cells which results in infections due to low white blood cells, bleeding due to low platelets, and anemia due to low red blood cells.

Gastrointestinal syndrome typically occurs at exposure doses of 600-1000 rad (6-10 Gy). Nausea, vomiting, loss of appetite, and abdominal pain are usually seen within one to two hours.

Neurovascular syndrome typically occurs at exposure doses greater than 1000 rad (10 Gy). It presents with neurological symptoms such as dizziness, headache, or decreased level of consciousness with an absence of vomiting.

The prodrome associated with ARS typically includes nausea and vomiting, headaches, fatigue, fever and short period of skin reddening. These symptoms may occur at radiation doses as low as 35 rad (0.35 Gy) and thus may not be followed by acute radiation sickness.

The radiation that was thought to be a problem years ago was a small amount of radiation that came from the Cathode Ray Tube or CRT in older monitors. There is no danger of radiation from LCD (or plasma to my knowledge) monitors. The only other radiation that I could think of that may prove to be harmful is the radiation given off by the wireless broadband cards used by cell phone companies.

It is usually supposed to be monitor of the computer that can emit radiations because of rays produced. It is hurtful for us. Take a look at Computer Radiations, Effects of computer radiations and also take a look at his Blurtit reference.

I am sitting next to a tower which holds the hard drives for the whole office. Is this detrimental to my health?

Discharged electro-static current sometimes called "waste current" from CRT.. It really goes with the light, the brighter would be your monitor the more hazardous it cause to you. Remember, eye strain due to the prolong exposure to screen?
Furthermore, if people thought they were already safe from radiation because of LCD monitor they thought it wrong.. LCD still produces heat courtesy of its electronic components, same with the heat produced inside our CPU, the only plus is lesser radiation.
I know this because I was victim of radiation and I have already experienced the effects of it. Dr. JPB

Here are the following effects of radiation contamination:

1. Dizziness and Nausea
2. Feel cold while experiencing perspiration (sweating)
3. Shirt sticks to skin as if skin becomes magnetic
4. Blisters and Inflammations itchy and increasing fast in sizes
5. Flu

Yet, when get into full sweating the flu is subsiding and blisters and inflammations too are getting smaller until they disappear. That is the signs you are recuperating. Dr. JPBarroga

As I know, every people who use computer receive a part of the radiation from the computer. The biggest influence receives our eyes. That's why it's really important to wear blue light blocking glasses when you are using your computer.

Computer emits radiations, it is effected to eyes, LCD screen is less harmful compare to CRT monitor because CRT tube emits much radiations.
