| 366813 | 2005-06-24 13:50:00 | Hi guys, I want to rearrange my room, but the way I want it, would have my head/body against a wall, the other side of which, is a TV. I remeber being told that this is a big no-no because any radiowaves (or whatever rays) go straight through the wall, into your head, f***ing you up. So, this being true, what can I do to prevent it? The wall my CRT backs onto has foil-lined gib so any radiation going that way gets reflected back to me, right? (separate question) So can I cover the back of the tv with foil, averting it downwards to stop myself getting radiation to the head...? Or something to that effect? cheers Rob |

| 366814 | 2005-06-24 16:05:00 | How Safe Are Home Sets Today? X-radiation emissions from properly operated and serviced home television receivers manufactured since about the middle of 1968 are generally at levels too low to present a public health hazard. FDA occasionally finds some TV receivers which fail to comply with the standard, however, and it requires corrective action by the manufacturer. I wouldn't be too worried about the radiation from your tv |

| 366815 | 2005-06-24 19:49:00 | yeh after all surely it has occurred to you that sitting in front of the tv/pc screen is surely worse cause the 'rays' are shooting towards you ? | drcspy (146) | ||

| 366817 | 2005-06-24 21:44:00 | If you are that worried get rid of your Cell phone and microwave oven as well. The levels are far to low to do any harm. Also wouldn't the TV be turned off when you are sleeping ? |

| 366818 | 2005-06-25 00:21:00 | Okay, misinformation is rife again . 1) X-ray emissions from TVs are below the threshold of naturally occurring x-radiation, i . e . virtually unmeasurable . 2) The back of a TV is a high-level source of 15 kHz VLF (very low frequency) electromagnetic fields . No harmful effects are recorded, but I would recommend that you adopt a "prudent avoidance" policy and either move the TV about 500mm away from the wall or put your feet at that end of the bed instead . The "radiation" from the rear of a TV is several times higher than the Swedish MPRII/MPRIII limit for VLF exposure . 3) Aluminium foil will not inhibit VLF magnetic fields to any worthwhile extent . It has no magnetic shielding properties, and any reduction would be due to eddy-current losses . 4) Microwave ovens do not "leak" microwave energy unless the door is bent, hinges damaged, door screen perforated, or the door-facings corroded or food-encrusted . They are, however, a high level source of ELF (50Hz) magnetic fields . 5) A digital cellphone is possibly the most dangerous source of electromagnetic radiation in common use . The transmission power is twice that of an analog phone, and the waveform of the output signal + modulation is very invasive . I have never heard an analog phone break into a normal phone line, or seen one interfere with other equipment, but you can hear a digital phone breaking into land-line phone calls, they interfere with many other items of electronic equipment including computer monitors, computers themselves (don't leave it too close to your computer, they can and do induce data corruption) and other digitally-based technology . Bear in mind that whnever switched on, your cellular phone transmits data at regular intervals even when you are not using it . I am not paranoid about electromagnetic radiation, I have spent most of my working life in low and high-frequency fields from sources at power levels varying from microwatts up to megawatts, but I limit my exposure as much as I can and will buy a digital phone only when the analog network finally closes down .

| 366819 | 2005-06-25 00:32:00 | ) X-ray emissions from TVs are below the threshold of naturally occurring x-radiation, i.e. virtually unmeasurable. thats assuming the tv is working correctly. i know a tech who had radition poisioning from sitting next to a faulty tv. (something about the HT going high which dramiticly increases the radiation output, so if your tv is permantly bright get it fixed!) |

| 366820 | 2005-06-25 03:05:00 | Just turn off the power to the house. But you'll have to move out of the house anyway because of the radon from the floor. And off the earth because of the high magnetic field (people complain about nanoteslas, when the earth's field is about 50 microtesla), and the RF fields from all the television transmitters and radio stations. And out of the solar system because of all the solar radiation (about 1 kW/m2 on the earth's surface). WE are all DEAD. :thumbs: |

Ah so that's what accounts for it . ;) |
