Mobile phone is a wonderful device that has already reached the hands of a large number of people in the world. Every technical excellence considers the health of the people and not the mobile phone. Various studies focus on the harmful effects of mobile phone radiation.

Just two decades ago, mobile technology came to the general public. Scientists were not completely understandable about the chronic health risk of this radiation. But the recent study has revealed the effect of radiation effects of mobile phones.

Some basic things

Magnetic field

A electromagnetic field consists of an electric field and a quadrangle. We also get induced by a magnetic field proportional to the current flowing through the electric line. Both areas have an effect on organisms, but the magnetic field is more harmful because it can easily penetrate into the living tissues. Small magnetic fields like one Micro Tesla (one millionth part) can have biological effects.

Scientists around the world have said that the children should avoid cell phone use and generally keep everyone alert so that the radiation loss can be reduced. They also say that using low SAR cell phones, increasing the use of headphones, avoiding the cell phone calls with weak signals and SMS instead of calls Increase the use.

For comparison, a mobile phone or a PDA can inspire you to magnetic vibrations, which are several times in the Micro Tesla, which are more than the harmful effects. The mobile phone is very close to the body and is always used. These devices are the most harmful sources of electromagnetic radiation

Frequency

Extremely low frequency (ELF) or ultra low frequency, which comes from power lines and home appliances, is more harmful. Where the activity of high frequency radio waves is very little or no activated, unless the low vibrations are activated and are vibrated (pulse) or expanded to propagated (amplitude modulated).

Both the mobile phones and the PDA emit the pulse radio wave (from the antenna) and the ELF (from the battery circuit).

Sar

The Specific Absorption Rate (SAR) is the power flow rate per watt (w / kg). It is the calculation of average energy or heat absorption in human tissue. Various countries of the world have different measurements for SAR tolerance. It changes between 0.6 to 1.6 watts / kg range.

For the majority of the body, the Federal Communications Commission of the United States (FCC) has set a safe range of 1.6 Watts / kg for SAR. This calculation has been done from the average response to tissues of different parts of the body.

The 'receptive power' of radiation is measured at Watt or DBM (desibilate ~ 1 ml). And the low power available for low frequency (low output power) for mobile phones is fixed. At present, most mobile operators reduce the output by 1 Watt (output power) to provide signal transmission by mobile antenna.

Biological effects

Various researchers report on the potentially harmful effects of mobile phones on health.

i. Influence on cardiovascular system (CVS)

Volunteers who were in the 900 MHz at 35 minutes RF-IMW (Radio Frequency-Electro Magnetic Wave), their blood pressure (both systolic and diastolic) increased 5-10 millimeters (mercury). Another study also showed that oxidative stress increased in the cardiovascular disease after having 900 MHz RF-IMD (30 minutes / day, 10 days).

ii. Impact on sleeping

EMF emitted from cell phones affects the brain. Healthy young men are waking up before sleeping for an average of 30 minutes (900 megahares; the specific absorption rate is 1 watt / kg), the IMF is applied.

Compared to the condition, compared to the previous condition, EEG's spectral capacities increase eye-to-eye movement during sleep. The sleeping startup section increases the maximum of 9.75-11.25 Hz and 12.5-13.25 Hz band.

iii. Local and general hostile effects

In a question-based study, there are some problems with using mobile phones (including about 17,000 people), such as ear heat (31%), fatigue (28%), headache (21.4%), decrease of attention (15% ), Headache (10%), memory loss (9%) and light body pain and depressed (6.7%). They suggested that these changes could be caused by the radio waves effect or the thermal effects of EMW. Those who hold these symptoms due to the use of mobile phones, 45% of them reduce the talk, change the model of the phone or reduce the harmful effects of using an integrated pest or landphone.

iv. Nerve hormone emission

Long-term use of the phone has adverse effects on nerve hormone emissions. Various groups of melatonin emissions have reported some conflicting reports. They concluded that talking long on the phone reduces melatonin production.

v. Calcium Leave and DNA Damage

The weak electromagnetic field leaves calcium from the cell membrane. Leaving calcium causes inflammation of the cells. This membrane inflammation causes DNA damage which gradually causes cancer.

vi. The father of the cancer

WHO has kept mobile phone radiation in the category of potential cancer. Many debates and research are still going on. This can be caused by the change of genes due to DNA damage. There is also a section that can release or stop genes based on external signals. DNA damage occasionally causes irregular increase in the cells which may become tumor.

vii. DNA damage: Reduce reproductive ability

If the DNA is broken, it is automatically fixed. However, there is no guarantee that it will return to its previous state. The results of a recent study of Dr. Ashok Agrawal and Cleveland of specialist of specialist of lernar college can be shown in the figure below.

In the process of myosis, the chromosomes in the pair pair together, so that the adjacent parts can be switched. But if this pattern of gene is changed by electromagnetic waves, then they can not be adjusted properly. Their examination revealed that the use of mobile phones more than four hours a day, the probability of sperm fertilization and mobility reduced by about 25 percent.

Which needs to be done

Scientists, public health experts and other government agencies around the world are saying that the children should avoid cell phone use and generally keep everyone alert so that radiation loss is reduced. They also say to increase the use of landphone, to use the low SAR cell phone, to avoid cellphone calls while having weak signal and to increase the usage of SMS instead of calls.

Conclusion

Cell phones have a huge contribution to make our lives easier. It has got popularity among young people. Unfortunately their risks are also high because they are getting more radiation exposure than others because they are compatible. Although there is debate whether non-miraging radiation is harmful to human health, many countries are taking preventive measures, and SAR levels have been set for cell phone manufacturers.
