Koliko vremena provodite na mobitelu? Znate li o opasnostima po zdravlje i rizicima mobilnih telefona jer emitiraju radio valove sve dok su uključeni? Budući da su sama osnova mobitela radio signali koji prenose glas, stalno ste izloženi tim radio valovima sve dok mobitel držite blizu tijela. Izloženost se višestruko povećava kada o tome govorite.

Kuhanje mozga: Zlo^(Evil) u mobilnim telefonima^{(Mobile Phones)} i tornjevima za mobitele^{(Cellphone Towers)}

Iako postoji nekoliko smjernica koje povezuju korištenje mobitela s bolestima kao što je rak, opasnosti korištenja mobilnih telefona i dalje postoje. Ovaj članak ispituje neke studije koje povezuju korištenje mobitela s različitim bolestima i opasnostima. Prije proučavanja opasnosti od mobitela, istražimo opasnosti života u područjima s tornjevima za mobitele.

^{(Cell Phone)}Tornjevi za mobitele: što bi mogao biti točan problem^{(Exact Problem)} ?

Još nije u potpunosti utvrđeno da su mobiteli stvarno opasnost, ali istraživači istražuju problem, a neki su pronašli jake poveznice koje kažu da život u području s visokofrekventnim tornjevima za mobitele može uzrokovati rak. Prema studiji koju je provelo India n Thermal Analysis Society ( ITAS ), tri slučaja raka pronađena su u istoj zgradi koja se nalazi nasuprot tornja za mobitele. Sva ova tri kućišta pripadaju apartmanima Usha Kiran^{(Usha Kiran Apartments)} nasuprot tornja za mobitele izgrađene u apartmanima Vijay^{(Vijay Apartments)} ( Carmicheal Road , Mumbai , Indija^(India) ). Ugledni indijski^(India) dnevni list Mid-dayje prenio članak o problemu stanovnika stana Usha Kiran^{(Usha Kiran Apartment)} koji pate zbog mobilnih tornjeva.

Na temelju različitih studija slučaja, ITAS je zaključio da su ljudi koji žive u radijusu od 50 do 300 metara od stubova mobitela izloženi većem riziku od bolesti zbog elektromagnetskog zračenja. Ovaj zaključak proizlazi iz činjenice da je u Indiji^(India) prihvatljivi standard zračenja 9,2W po kvadratnom metru. Za druge zemlje, "opasna zona" je drugačija - na temelju njihovog prihvatljivog standarda zračenja. Za SAD je 580 – 1000 mikro-wata po kvadratnom centimetru. To znači da su ljudi koji žive u krugu od 2 do 2,5 milje u radijusu od stubova za mobitele izloženi opasnosti po zdravlje.

 

U još jednom incidentu, stanovnik New Delhija^{(New Delhi)} ( Indija^(India) ) nedavno je podnio peticiju da se tvrtkama za mobitele zabrani podizanje bilo kakvih tornjeva za mobitele unutar 50 metara od škola, bolnica i stambenih područja. Prema njegovim riječima, njegov sin je dobio rak zbog tornja za mobitel koji mu je podignut na kući. Kaže da su se u roku od godinu dana od postavljanja tornja svi u njegovoj obitelji udebljali i počeli patiti od problema sa spavanjem. Ova priča je također bila^(India) pokrivena u vrijeme^(Time) Indije .

U studiji koju je proveo Njemački institut za biologiju zgrada^{(Building Biology Institute of Germany)} , oni navode da je sve iznad 10 mikro-wata po četvornom metru zabrinjavajuće^(concern) jer će utjecati na biološke stanice u svim vrstama života – biljkama, životinjama i ljudima. Za tornjeve koji emitiraju više od 10 mikrowata po kvadratnom centimetru, studija klasificira zabrinutost zbog izloženosti kao ozbiljne^(severe) .

Znanstvenici i istraživači okrivljuju elektromagnetsko zračenje radio valova kao agense koji povećavaju rizik od raka kod ljudi koji koriste mobitele – osobito kod djece. U slučaju tornjeva za mobitele, ljudi koji žive u obližnjim područjima stalno su izloženi visokom elektromagnetskom zračenju. Budući da je elektromagnetsko zračenje odgovorno za promjene u funkcioniranju bioloških stanica i tkiva, ti ljudi su pod većim rizikom od dobivanja radijacijskih bolesti.

Opasnosti po zdravlje mobitela

Među glavnim problemima koji se nalaze kod ljudi koji žive u blizini stubova za mobitele su:

1. Rakovi,
2. Tumori, posebno, Gliomi
3. suho oko,
4. Problemi s mišićima
5. Oštećenje mozga – ovisno o tome koliko tvrtki za mobitele koristi određeni toranj za mobitele. ITAS tvrdi da što veći broj mobilnih tvrtki dijeli jedan toranj, to su veće opasnosti od stubova za mobitele.

Specifična stopa apsorpcije^{(Specific Absorption Rate)}

Specifična stopa apsorpcije – ili SAR kako je poznata – odnosi se na stopu elektromagnetske energije koju ljudsko tijelo apsorbira pri korištenju mobitela i drugih uređaja koji emitiraju radio valove. Mjeri se u vatima^(Watts) po kg ljudskog tkiva. Ako je SAR ograničenje za mobitele 1,6 W/kg (kao u SAD-u), ukupno vrijeme koje osoba može koristiti mobitelom je najviše 6 minuta. S obzirom na marginu pogreške od 3, ukupno vrijeme koje osoba može koristiti mobitelom iznosi samo 20 minuta dnevno.

Dok su neke zemlje sada postavile obvezu prikazivanja SAR vrijednosti mobitela na svojim mobilnim telefonima, druge se još nisu probudile na opasnosti korištenja mobitela. Wikipedia ima još neke informacije o SAR -u, uključujući jednadžbu za izračunavanje SAR -a .

Mobiteli – koje su opasnosti?

Prema Nacionalnom institutu za rak^{(National Cancer Institute)} ( SAD^(USA) ), postoje dvije vrste elektromagnetskog zračenja – ionizirajuće i neionizirajuće^{(ionizing and non-ionizing)} . Prvi tip nalazimo u X-zrakama itd., a dokazano je da uzrokuju teške bolesti kod ljudi koji su izloženi takvim emisijama. Mobiteli emitiraju neionizirajuće zračenje koje uhvate biološke stanice i tkiva koja su u izravnom kontaktu s mobitelom – ruke i uši. Nacionalni institut za rak^{(National Cancer Institute)} kaže da nema dokaza da mobiteli zapravo mogu povećati rizik od raka, ali ipak mogu povećati temperaturu tjelesnih stanica u kontaktu s mobitelima.

U drugoj studiji dr. Girisha^{(Dr. Girish)} iz Indian Thermal Analysis Society , ljudsko tijelo se sigurno drži u mikrovalnoj pećnici od 700-1000 W samo 19 minuta. To znači da ljudi mogu razgovarati na mobitelu samo 19 minuta^{(19 minutes)} bez ikakve štete.

Proučavanjem štakora također je utvrđeno da dugotrajno izlaganje elektromagnetskom zračenju može dovesti do teških oštećenja mozga. Ljudi koji koriste mobilne telefone na određenoj strani mozga imaju veći rizik od oštećenja te strane mozga - što dovodi do složenih poremećaja koji mogu, ali i ne moraju biti reverzibilni.

Prema dr. Keithu Blacku^{(Dr. Keith Black)} , predsjedniku^(Chairman) odjela za neurologiju u medicinskom centru Cedars-Sinai u Los Angelesu:^{(Neurology at Cedars-Sinai Medical Center in Los Angeles:)}

What microwave radiation does in most simplistic terms is similar to what happens to food in microwaves, essentially cooking the brain. So in addition to leading to a development of cancer and tumors, there could be a whole host of other effects like cognitive memory function, since the memory temporal lobes are where we hold our cell phones.

Zbog promjena u električnim aktivnostima mozga, ljudi mogu patiti od sljedećih problema:

1. Napadaji
2. Paraliza
3. Moždani udar
4. Psihoza
5. Kardiovaskularni problemi

Među ostalim velikim problemima koji su povezani s prekomjernom upotrebom mobitela su:

1. Oštećene krvne žile što znači gubitak zaštite mozga
2. Rak
3. Tumor mozga, posebno gliomi
4. Oštećenje DNK – što rezultira tumorima i rakom
5. Poremećaji spavanja
6. Nepovratna plodnost
7. Problemi s kožom^(Skin) – uzrokovani uglavnom pregrijavanjem stanica i uključuju osip, rane, pa čak i tumore kože
8. Gubitak sluha^(Hearing) zbog pregrijavanja bubnjića
9. Oštećenje crvenih krvnih stanica – usporavanje cirkulacije krvi, a time i izloženost drugim bolestima

Opasnosti korištenja mobitela^(Cellphones) kod djece^(Children)

Djeca^(Children) su pod većim rizikom oboljevanja od prekomjerne upotrebe mobitela jer je njihova lubanja tanka u odnosu na odrasle. Djeca^(Children) koja prekogranično koriste mobitele susreću se s velikim rizikom od oštećenja mozga – zbog povećanog zagrijavanja moždanih stanica – osim rizika gubitka sluha i vida.

Možda smo kasnije u životu počeli koristiti mobitele, ali danas djeca od 10 do 12 godina žele mobitel i imaju ga. Njihova upotreba je nekontrolirana. Nitko više ne želi koristiti fiksni telefon... Što će se dogoditi nakon 20 i 30 godina? Samo će vrijeme pokazati. Možemo se samo nadati da to nije tempirana bomba koja će eksplodirati kada današnja djeca budu imala 50 i 60 godina…^{(We may have started using mobile phones later in life, but these days children right from the age of 10 and 12 want a mobile phone and have one. Their usage is uncontrolled. No one wants to use a landline anymore… What will happen after 20 and 30 years? Only time will tell. We can only hope that it is not a time-bomb which will explode when today’s children are 50 and 60 years old …)}

Svjetska zdravstvena organizacija^{(World Health Organization)} rekla je u svibnju 2011.^{(May 2011)} da mobilni telefoni mogu uzrokovati rak i druge zdravstvene opasnosti te je pozvala korisnike telefona "da ograniče svoju upotrebu i poduzmu pragmatične mjere za smanjenje izloženosti mobitelima". Zaključeno je da je upotreba mobilnih uređaja “možda kancerogena za ljude”, što je izraz koji mobitele stavlja u sredinu ljestvice ocjenjivanja koja sadrži 5 razina kancerogenih tvari, a mobitele rangira odmah ispod stvari za koje se definitivno zna da uzrokuju rak kao što je pušenje!

Mobile Phones Health Hazards, Risks and Dangers

How much time do you spend on your cell рhone? Do you know the mobile phones’ health hazards and risks caused because they keep on emitting radio waves аs long as they are switched on? Since the very basis of cellphones is radіo signals that carry voice, you are in constant exposure to these radio waves as long as you keep the cell phone near your body. The exposure іncreases manifold when you are talking about it.

Cooking The Brain: The Evil In Mobile Phones & Cellphone Towers

Though there are few pointers that link cell phone usage to diseases such as cancer, the dangers of using mobile phones still exist. This article examines some studies that link the usage of cellphones to different diseases and dangers. Before studying cell phone dangers, let us explore the hazards of living in areas having cell phone towers.

Cell Phone Towers: What Could Be The Exact Problem?

It has not yet been completely established that cell phones are really a danger but researchers are exploring the issue, and some have found strong links that say living in an area with cell phone towers with high frequency can cause cancer. According to a study conducted by the Indian Thermal Analysis Society (ITAS), three cancer cases were found in the same building that lies opposite to a cell phone tower. All these three cases belong to Usha Kiran Apartments opposite to cellphone tower built on Vijay Apartments (Carmicheal Road, Mumbai, India). A prominent Indian daily Mid-day had carried an article on the issue of Usha Kiran Apartment residents suffering due to mobile towers.

Based on different case studies, the ITAS concluded that people living within a 50 to 300-meter radius of cell phone towers are at higher risk of diseases due to electromagnetic radiation. This conclusion derives from the fact that in India, an acceptable standard of radiation is 9.2Watt per square meter. For other countries, the “danger zone” is different – based on their acceptable standard of radiation. For the US, it is 580 – 1000 Micro-Watts per square centimeter. This translates that people living within 2 to 2.5 miles in the radius of cell phone towers are at risk of health hazards.

 

In yet another incident, a resident of New Delhi (India) recently filed a petition to ban cellphone companies from erecting any cell phone towers within 50 meters of schools, hospitals, and residential areas. According to him, his son got cancer due to a cell phone tower that was erected on his house. He says within a year of the tower being installed, everyone in his family gained weight and started suffering from sleeping problems. This story was also covered in the Time of India.

In a study conducted by Building Biology Institute of Germany, they state that anything above 10 Micro-Watt per square meters is a matter of concern as it will affect the biological cells in all kinds of lives – plants, animals, and humans. For towers that emit more than 10 microwatts per square centimeter, the study classifies exposure concerns as severe.

Scientists and researchers blame the electromagnetic radiation from radio waves as agents that increase the risk of cancer in people using cell phones – especially in children. In the case of cell phone towers, people living in nearby areas are constantly exposed to high electromagnetic radiation. Since electromagnetic radiation is responsible for alterations in the functioning of biologic cells and tissues, these people are at a greater risk of acquiring radiation diseases.

Mobile phones health hazards

Among the major problems found in people living near cellphone towers are:

1. Cancers,
2. Tumors, in particular, Gliomas
3. Dry Eye,
4. Muscle problems
5. Damage to the brain – depending upon how many cell phone companies are using a particular cell phone tower. ITAS claims that the more number of cellphone companies sharing a single tower, the greater the hazards of cell phone towers.

Specific Absorption Rate

The specific absorption rate – or SAR as it is known – refers to the rate of electromagnetic energy that is absorbed by the human body when using cell phones and other devices emitting radio waves. It is measured in Watts per Kg of human tissue. If the SAR limit of cell phones is 1.6W/Kg (as in the US), the total time that a person can use cellphones is a maximum of 6 minutes. Given an error margin of 3, the total time a person can use cellphones translates to only 20 minutes per day.

While some countries have now made it mandatory to display the SAR value of cell phones on their handsets, others have not yet woken up to the dangers of using cellphones. Wikipedia has some more information on SAR including the equation to calculate SAR.

Cellphones – What Are The Dangers?

According to the National Cancer Institute (USA), there are two types of electromagnetic radiations – ionizing and non-ionizing. The first type is found in X-Rays etc, and it has been proved that they cause severe diseases in people who are exposed to such emissions. Cellphones emit non-ionizing radiations that are picked up by biological cells and tissues that are directly in contact with cellphones – hands and ears. The National Cancer Institute says there is no proof that cellphones can actually increase the risk of cancer but still, it can increase the temperature of body cells in contact with cellphones.

In another study by Dr. Girish of the Indian Thermal Analysis Society, a human body is safely kept in a microwave oven of 700-1000W for only 19 minutes. This means that people can carry on a cell phone conversation only for 19 minutes at a time without harming themselves.

It has also been found by studying rats that prolonged exposure to electromagnetic radiation can lead to severe brain damage. People using cellphones to a particular brain side have more risk of damaging that side of the brain – leading to complex disorders that may or may not be reversible.

According to Dr. Keith Black, Chairman of Neurology at Cedars-Sinai Medical Center in Los Angeles:

What microwave radiation does in most simplistic terms is similar to what happens to food in microwaves, essentially cooking the brain. So in addition to leading to a development of cancer and tumors, there could be a whole host of other effects like cognitive memory function, since the memory temporal lobes are where we hold our cell phones.

Due to the changes in the electrical activities of the brain, people can suffer from the following problems:

1. Seizures
2. Paralysis
3. Stroke
4. Psychosis
5. Cardiovascular problems

Among other major problems that have been linked to excessive cell phone usage are:

1. Damaged blood vessels that translate to the loss of protection to the brain
2. Cancer
3. Brain Tumor, esp Gliomas
4. DNA damage – resulting in tumors and cancers
5. Sleep disorders
6. Irreversible fertility
7. Skin problems – caused mainly by overheating of cells and include rashes, sores, and even skin tumors
8. Hearing loss due to overheating of eardrums
9. Damage to red blood cells – slowing down blood circulation and thereby exposure to other diseases

Dangers of Using Cellphones in Children

Children are at a greater risk of procuring diseases from the excessive usage of cell phones because their skull is thin compared to adults. Children using cell phones beyond limits run into a major risk of procuring brain damage – due to increased heating of brain cells – other than risking a loss in hearing and vision.

We may have started using mobile phones later in life, but these days children right from the age of 10 and 12 want a mobile phone and have one. Their usage is uncontrolled. No one wants to use a landline anymore… What will happen after 20 and 30 years? Only time will tell. We can only hope that it is not a time-bomb which will explode when today’s children are 50 and 60 years old …

The World Health Organization said in May 2011 that mobile phones might cause cancer and other health hazards and urged phone users “to limit their use and take pragmatic measures to reduce exposure to mobiles”. It concluded that mobile use is “possibly carcinogenic to humans’, a term that places mobiles in the middle of the rating scale that contains 5 levels of carcinogens, and ranked mobiles just below things definitely known to cause cancer such as smoking!

Mobile phones Safety advice:

1. For talking, keep your cell phone away from the body.
2. Use some hands-free devices such as earphones or Bluetooth while communicating.
3. Do not keep cell phones on the body while talking.
4. Use more of landline phones as they use analog signals.
5. Try texting as an alternative to talking on cell phones.
6. Try not to talk on the mobile phone for more than 15 minutes at a time.
