Task 1. Read the text “MOBILE PHONES” and translate.
Is talking on a mobile phone hazardous to your health? It is difficult to know for sure. Some research suggests that heavy users of mobile phones are at a greater risk of developing brain tumours. However, many other studies suggest there are no links between cancer and mobile phone use.
The main problem with the current research is that mobile phones have only been popular since the 1990s. As a result, it is impossible to study the long term exposure of mobile phone use. This concerns many health professionals who point out that many cancers take at least ten years to develop. Another concern about these studies is that many have been funded by those who benefit financially from the mobile phone industry.
Many cancers take 10 years to develop.
Over three billion people use mobile phones on a daily basis, and many talk for more than an hour a day. Mobile phone antennas are similar to microwave ovens. While both rely on electromagnetic radiation, the radio waves in mobile phones are lower in radio frequency (RF). Microwave ovens have enough RF to cook food and are therefore known to be dangerous to human tissues. However, the concern is that the lower frequency radio waves that mobile phones rely on may also be dangerous. It seems logical that holding a heat source near your brain for a long period of time is a potential health hazard.
Mobile phones get hot when they are used for a long period of time.
Some researchers believe that other types of wireless technology may also be dangerous to human health, including laptops, cordless phones, and gaming
consoles. Organizations that are concerned about the effects of Electromagnetic Radiation (EMR) suggest replacing all cordless devices with wired ones. They say that many cordless phones emit dangerous levels of EMR even when they are not in use. They even suggest keeping electronic devices, such as computers and alarm clocks out of bedrooms, or at least six feet from your pillow.
Other wireless technology may also be hazardous to our health.
A growing number of health professionals worldwide are recommending that mobile phone users err on the side of caution until more definitive studies can be conducted. They recommend that adults use head sets or speaker phones and that children and teens, whose brain tissue are still developing, use mobile phones only for emergencies. Concerned medical experts use the example of tobacco to illustrate the potential risks. Many years ago, people smoked freely and were not concerned about the effects of cigarettes on their health. Today, people know that cigarettes cause lung cancer, though it is still unknown exactly how or why. Some doctors fear that the same thing will happen with devices such as mobile phones
Mobil telefondan gaplashish sog'lig'ingiz uchun zararli hisoblanadimi? Bu haqda aniq xulosa chiqarish qiyin. Ba'zi tadqiqotlarga ko'ra, mobil telefonlardan faol foydalanuvchilar miyada o'smalar paydo bo'lish xavfiga duchor bo'lmoqdalar. Ammo, ko'plab boshqa tadqiqotlar mobil telefonlardan foydalanish va saratonga aloqasi yo'qligini ko'rsatmoqda.
Joriy tadqiqotlardagi asosiy muammo shundaki, mobil telefonlar ommaviy tarzda faqatgina 1990-yillardan boshlab ishlatila boshlangan. Natijada, mobil telefonlardan uzoq muddatli foydalanish ta'sirini o'rganib bo'lmaydi. Bu holat ko'plab sog'liqni saqlash mutaxassislarini tashvishga solmoqda, chunki ko'pchilik saratonlar kamida o'n yildan keyin rivojlanadi. Ushbu tadqiqotlarni xavotirga solayotgan boshqa bir muammo shundaki, ularning ko'pchiligi mobil telefon sanoatidan moliyaviy manfaatdor bo'lganlar tomonidan moliyalashtirilgan.
Saratonning rivojlanishi 10 yilgacha cho'zilishi mumkin.
Uch milliarddan ortiq odamlar kundalik ravishda mobil telefonlardan foydalanadilar va ko'pchiligi bir soatdan ortiq gaplashadi. Mobil telefon antenalari mikroto'lqinli pechkalarga o'xshaydi. Ikkala qurilma ham elektromagnit nurlanishiga amal qiladi, ammo mobil telefonlardagi radio to'lqinlar past chastotaliga ega. Mikroto'lqinli pechkalar oziq-ovqatlarni pishirish uchun yetarli chastotaga ega bo'lgani uchun inson to'qimalariga xavfli hisoblanadi. Ammo mobil telefonlarda foydalanadigan past chastotali radio to'lqinlar ham xavfli bo'lishi mumkinligi xavotirga solmoqda. Qizdirgichni uzoq vaqt miyangizga yaqin tutish mantiqan sog'liq uchun potentsial xavf tug'dirishi mumkin.
Mobil telefonlar uzoq vaqt ishlatilib qizib ketadi.
Ba'zi olimlar shuningdek, noutbuklar, simsiz telefonlar va o'yin pristavkalari kabi boshqa simsiz texnologiyalar inson sog'ligi uchun xavfli bo'lishi mumkinligiga ishonmoqdalar. Elektromagnit nurlanishining (ENU) ta'siridan xavotirga tushgan tashkilotlar barcha simsiz qurilmalarni simli uskunalar bilan almashtirish kerakligini tavsiya etmoqdalar. Ular ko'plab simsiz telefonlar hatto ular ishlatilmaganda ham xavfli darajada ENU nurlanishini aytmoqdalar. Ular hatto elektronika qurilmalarini, jumladan, kompyuterlar va budilnikni ham yotoqxonadan olib chiqish yoki kamida yostiqqacha 6 futgacha masofada saqlash kerakligini tavsiya qilmoqdalar.
Boshqa simsiz texnologiyalar ham sog'ligimiz uchun xavfli bo'lishi mumkin.
Butun dunyodagi sog'liqni saqlash mutaxassislarining ortib borayotgan soni mobil telefonlardan foydalanuvchilarga oldindan ehtiyotkor bo'lishni tavsiya qilmoqda, chunki hali aniqroq tadqiqotlar o'tkazilmagan. Ular kattalar uchun naushniklardan yoki ovozli aloqadan, bolalar va o'smirlar uchun esa, miyalar hali shakllanib ulgurmagan davrda mobil telefonlardan faqat favqulodda vaziyatlardagina foydalanish kerakligini tavsiya qilmoqdalar. Tashvishga tushgan shifokorlar ushbu potentsial xatarlarni tamaki chekish misolidagiga o'xshatmoqdalar. Bir necha yil avval odamlar xavotirsiz tamaki chekar va tamakining sog'ligiga ta'siri haqida tashvish tortmasdilar. Bugungi kunda tamaki o'pka saratoniga olib kelishi ma'lum bo'ldi, ammo uning tuzilishi yoki sabablari hali noma'lum. Ba'zi shifokorlar mobil telefonlar va boshqa shunga o'xshash qurilmalar bilan xuddi shunday vaziyat sodir bo'lishidan xavotirdalar.
