All electric current generates electric and magnetic fields. The electric field is proportional to the voltage and magnetic field is proportional to the current. That is clearly understood, the voltage is similar to the amount of water in a tank and the current is the force that down the pipe. In the alternating current of our homes, the direction of the stream changes 60 times for each second. Electric fields can be shielded or isolated, for example with insulating coating of cables, While the magnetic field is much more difficult and expensive to isolate and in many cases it is virtually impossible. Buried underground power lines generate magnetic fields weaker than those generated by cables that are in the open air. This occurs by design and not because the Earth eliminates the field. In any case, the best way to reduce the magnetic field is increasing the distance separating us from energy supplies, including the electric pots. The electric force lines include transmission lines mounted on metal towers and distribution lines mounted on wooden poles or concrete. Transmission lines generate strong electric and magnetic fields, While distribution lines generate relatively weaker fields depending on the number of houses that supplied energy. Studies in humans have shown that electric and magnetic fields found in the homes and offices are not intense enough to cause health damage. But it remains an open question whether permanent and continuous exposure to weak fields is harmful to people, There is not enough evidence to confirm this. However, studies of laboratory animals and cell cultures have shown that weak fields can have effects on different biological processes, for example they can alter the hormones and enzymes levels and the pace of the movement of some chemicals in living tissue. By themselves these changes doesn't seem to be a health hazard, but it is not known if in the long term they may be cause of an increase in the incidence of cancer or other adverse life. Only in some studies carried out in Europe, United States, Japan and Australia, the effects of these fields have caused an impact on the growth of cancer in laboratory animals. Some of these studies have reported that children who have lived close to transmission lines of high current and distribution lines, they have higher incidences of cancer. The same, other studies have come to the conclusion that adults exposed to lines of Haute tension have experienced one higher incidence of the disease, than those which have not been crags that kind of radiation. Other studies have come to the conclusion that no compelling results, but the level of uncertainty is high. Finally other studies show that there is no apparent cause of association that deny or confirm the possibility of harm to health. In the case of pregnant women, tentative studies have resulted that the possibilities of risky pregnancies are higher which boasted it. Take precautionary measures, for example not using an electric blanket for sleep, but warming up the bed with the blanket before one lying down and off to go to bed. Can also move the bed of a wall close to a power source and watching the TV or computer monitor where less each 50 cm distance. Despite the fact that the studies are not conclusive, international health agencies recommend avoiding magnetic fields, especially those caused by high voltage lines, substations, Air transformers and power transmission and distribution lines. Citizens are in full right to require that the high-voltage lines and transformers are away from their homes. In our country, where are the transmission and distribution lines usually installed outdoors and in many cases close to housing, they constitute an attack on health, the Government has an obligation to correct and citizens have the right to demand that it should be corrected. In the Decade of the 80, in United States, several States took measures in this respect and there were many instances of lawsuits against the companies of electricity by air facilities nearby homes. The Economist magazine published a study of the University of Colorado showing a picture of 344 children who died of cancer after living near power lines against a sample of control of others 344 healthy children who never suffered this disease. In that decade in Florida where the demands were many, the federal Government of that State was one of the first to regulate this type of facilities. A pathetic case was the one which occurred in an American city where all children attending a park where it was installed a substation outdoor, They ill cancer to the brain. In Lima, examples of these high-voltage lines that cross the city are those found in the Av. The Navy, between the Av. I escardó and up to the height of the craft market on the block 7, from where the line goes underground. Examples of distribution lines are seen in almost all the streets of Lima where as cobwebs of two species of Arachnids, electricity undertakings and telephones, They disfigure the city and threaten the health of citizens. It is not the fault of the current municipal authorities that high voltage line come from the Faucett Avenue crossing Maranga, because that was the fault of those who were in the municipality of Lima at the time that projected bliss Avenue and urbanization. What is the duty of the municipality of Lima, It is to give her term to electricity companies to begin to bury the lines, as befits a city of the century 21

Gach leictreachas a ghintear réimsí leictreacha agus maighnéadacha. Is é an réimse leictrigh i gcomhréir leis an voltas agus is é an réimse mhaighnéadaigh comhréireach leis an reatha. I gcás go bhfuil sé soiléir, voltais atá cosúil leis an méid uisce in umar agus an sruth é an fórsa a an píopa síos. I alternating reatha ár dtithe, an treo na n-athruithe atá ann faoi láthair 60 uair in aghaidh an dara. Is féidir le réimsí leictreacha a mbí nó scoite amach, mar shampla, leis an sciath cábla inslithe, cé go bhfuil an réimse maighnéadach i bhfad níos deacra agus costasach a leithlisiú agus i go leor cásanna go bhfuil sé beagnach dodhéanta. Línte cumhachta faoi thalamh faoi thalamh a ghiniúint réimsí maighnéadacha níos laige ná iad siúd a chruthaíonn na cáblaí atá amuigh. Tá sé seo ag dearadh agus toisc nach bhfuil eliminates an domhain ar an réimse. In aon chás, Is é an bealach is fearr chun laghdú ar an réimse maighnéadach ag méadú an t-achar a scarann sinn ó na soláthairtí cumhachta, lena n-áirítear fearais leictreacha. Áirítear ar na línte cumhachta línte tarchuir agus dáilte línte piolóin suite ar suite ar chuaillí adhmaid nó coincréit. Ghiniúint línte tarchuir réimsí leictreacha agus maighnéadacha láidir, fad a ghintear línte dáilte réimsí réasúnta lag ag brath ar líon na dtithe a sholáthar ar na cumhachta. Staidéir i ndaoine a thaispeáint nach nach bhfuil réimsí leictreacha agus maighnéadacha le fáil i dtithe agus in oifigí dian go leor a bheith ina chúis damáiste don tsláinte a. Ach tá sé fós ina ceist oscailte cibé an nochtadh buan agus go leanúnach le réimsí lag nó nach bhfuil díobhálach do dhaoine, le haghaidh bhfuil dóthain fianaise ann chun a dheimhniú dóibh. Mar sin féin, Léiríonn staidéir in ainmhithe agus i gcultúir Saotharlainne cille gur féidir le réimsí lag go mbeidh éifeachtaí ar na próisis bitheolaíochta éagsúla, mar shampla is féidir, a athrú hormóin agus leibhéil einsím agus ráta na gluaiseacht ceimiceán áirithe i bhfíochán beo. De féin nach bhfuil na hathruithe seo dealraitheach a bheith ina guais sláinte, ach tá sé fios cibé an féidir go fadtéarmach faoi deara méadú ar mhinicíocht ailse nó éifeachtaí díobhálacha ar an saol eile. Níl ach cúpla staidéir a rinneadh san Eoraip, Stáit Aontaithe, An tSeapáin agus an Astráil, na héifeachtaí de na réimsí sin ba chúis le méadú ar mhinicíocht ailse in ainmhithe saotharlainne. Tá cuid de na staidéir a thuairisciú go bhfuil leanaí a bhí ina gcónaí in aice le línte tarchurtha agus línte dáilte ard atá ann faoi láthair, Tá ráta ailse níos airde. Chomh maith céanna, staidéir eile curtha i gcrích go bhfuil daoine fásta faoi lé línte ardvoltais fhulaing minicíocht níos airde de na galair, iad siúd nach bhfuil a expusto an gcineál seo radaíochta. Staidéir eile curtha i gcrích nach raibh aon torthaí dochloíte, ach tá an leibhéal ard neamhchinnteachta. Mar fhocal scoir, taispeánann staidéir eile a chur faoi deara aon chomhlachas léir a dhiúltú nó a dhaingniú ar an bhféidearthacht a bhaineann le damáiste don tsláinte. I gcás na mná torracha, Staidéir Sealadach a bheith mar thoradh ar an seans toircheas risky atá níos airde ná mar a glacadh leis. Ba chóir go dtógfadh sé bearta réamhchúraim, Ní mar shampla, ag baint úsáide as blaincéad leictreach a chodladh, ach teasa an leaba le pluid roimh dul a chodladh agus ag casadh sé amach chun dul a chodladh. Is féidir leat dul chomh maith ar an leaba de bhalla in aice mar fhoinse cumhachta agus ag faire ar an monatóireacht a dhéanamh ar an teilifís nó ar ríomhaire amháin ar a laghad 50 cm ar shiúl. Cé go bhfuil staidéir neamhchonclúideach, mholadh gníomhaireachtaí sláinte idirnáisiúnta a sheachaint réimsí maighnéadacha, go háirithe iad siúd de bharr línte cumhachta, fostáisiúin, Claochladáin Aeir agus línte tarchuir agus dáilte leictreach. Do Shaoránaigh Tá gach ceart a éileamh go bhfuil na línte cumhachta agus trasfhoirmeoirí amach as a dtithe. Is é ár dtír, i gcás go ginearálta na línte tarchuir agus dáilte suiteáilte lasmuigh agus i go leor cásanna gar don bhaile agus, ina mbaol do shláinte, go bhfuil an rialtas oibleagáid a cheartú agus saoránaigh an ceart chun a cheangal ar cheartú. Sna deich mbliana ar an 80, US, Deir Bhí roinnt beart ar sé, agus bhí go leor cásanna de lawsuits i gcoinne cuideachtaí cumhachta do shuiteálacha aerga gar do thithíocht. An iris Eacnamaí fhoilsigh staidéar ag an Ollscoil Colorado léiríonn pictiúr de 344 páistí a fuair bás den ailse tar éis cónaí in aice le línte cumhachta i gcoinne sampla eile a rialú 344 leanaí sláintiúil a riamh taithí acu an galar. Sa deich mbliana i Florida áit a raibh na héilimh iomadúla, Bhí an rialtas cónaidhme an stáit seo ar cheann de na saoráidí den sórt sin go rialta den chéad uair. Ba cás pathetic an cás i gcathair Meiriceánach ina go léir ar na páistí a chuaigh go dtí ar pháirc ina suiteáilte sé fostáisiún lasmuigh, tinn le hailse inchinn. I Lima, Samplaí de línte cumhachta sin a thrasnaíonn an chathair le fáil i VA. La Marina, idir an Av. Weeded agus fiú an airde ar an margadh ceardaíochta ar an mbloc 7, ó áit a dtéann an líne faoi thalamh. Samplaí de na línte dáilte atá le feiceáil i mbeagnach gach áit ar na sráideanna de Lima mar gréasáin de dhá speiceas de arachnids, fóntais leictreacha agus teileafóin, ó dhealramh na cathrach agus le sláinte shaoránaigh an bhagairt. Nach bhfuil an locht na n-údarás bardasach atá ann faoi láthair a thagann go bhfuil cumhacht ag an líne ó ar fud Avenida Faucett Maranga, toisc go raibh an locht ar sin i Bardas de Lima ag an am sin an ascaill agus uirbiú réamh-mheasta. Cad é an oibleagáid ar an Bardas de Lima, téarma é a thabhairt do chuideachtaí chumhacht chun tús a adhlacadh na línte, mar befits chathair de na céad 21
