The radio waves have longer wavelengths than infrared waves. Radio waves are a kind of electromagnetic radiation. In the electromagnetic spectrum, the radio waves lie between the frequencies from 300 GHz to as low as 3 kHz. Moreover, the respective wavelengths range from 1 millimetre to 100 kilometres.
Generally, the artificial radio waves are generated by the experts and are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, etc. Various effects of electromagnetic radiation on the human body are given below. Radio waves generated by radio contain the lowest frequencies in the electromagnetic spectrum and are much safer.
Major effects on general health issues:
Generally, symptoms of low levels of exposure to electromagnetic fields are attributed by the public itself at their homes. The observed symptoms include headaches, anxiety, suicide and depression, nausea, fatigue and loss of libido.
Generally, the X-rays and Gamma rays have the tendency to cause severe damage to your body. The excess exposure to these rays can damage the DNA and cells. These rays can also cause sickness, burns, or cancer.
The non-ionizing radio waves do not have enough protons to break the cells or damage DNA. These include the radio waves which are emitted by the mobile phone and do not emit high energy radiations and are probably safe up to a great extent.
High Exposure to the electromagnetic fields at several environmental levels does not increase the risk of any adverse outcome such as spontaneous abortions, malformations, low birth weight, and congenital diseases. Conditions such as prematurity and low birth weight in children of workers are not scientifically proven that these are caused by the field exposures.
The people who are exposed to high levels of radiofrequency and microwave radiation generally suffer from General eye irritation and cataracts. But there is no evidence that these effects occur at levels experienced by the general public.
Cancer and Electromagnetic fields
The effects of electromagnetic fields and its evidence for any effect remains highly controversial. There is not found any large increases in risk have been found for any cancer in children or adults. There is a small increase in the risk of childhood leukaemia with exposure to low-frequency magnetic fields in the home.
Moreover, it is not scientifically proven that these results indicate a cause-effect relationship between exposure to the fields and disease. At very high temperatures the RF waves can heat the body tissues. The RF waves emitted from mobile phones are unlikely to cause cancer as these are non-ionizing waves and have a very low tendency to damage the DNA.
Depression and Electromagnetic hypersensitivity
There is some very minor evidence to support the idea of electromagnetic hypersensitivity. It shows that individuals do not show consistent reactions under properly controlled conditions of electromagnetic field exposure. There is not any biological mechanism to explain hypersensitivity.
Effect on the nervous system
It is a topic for active discussion from a very long time radio waves are reported to affect isolated nerve preparations, the central nervous system, brain chemistry and histology, and the blood-brain barrier. Recently, the experts have done a study on isolated heart preparations have provided evidence of bradycardia as a result of exposure to RF radiation at non-thermal power densities.
Visual issues caused by radio waves
For more than 30 years, cataract development is observed as a result of high exposure of the eye to the radio waves. Also, the CW microwave fields have similar thresholds for producing cataracts.
Generally, after the termination of the RF exposure, the alteration of hormone concentrations is reversible. The systems which are important in the maintenance of the homeostasis alter the complex interactions of the hypothalamic, pituitary, adrenal, and thyroid systems.
The effect of radio waves is reported in both Vitro and Vivo test systems. Moreover, the Lymphoblast transformation and changes in responsiveness to mitogens have also been noticed. Generally, sinusoidal ELF fields have no significant effects on immune competence after in vivo exposure of some laboratory animals.
Hematologic and Cardiovascular Systems
Many scientists have put a lot of efforts to assess the effects of both thermogenic and non-thermogenic levels of RF radiation on blood chemistry and blood-cell counts. No blood characteristics measured in the study were found to change in response to chronic RF exposure.
Only some studies have proven some evidence of possible carcinogenic potential, and others have shown no effect. Plus, all the studies were proven with electromagnetic fields larger than the relevant GWEN fields. The interpretation of some reports is complicated by thermally induced stress.
The electromagnetic waves of high frequencies can affect your body in a much adverse manner than the waves with lower frequencies. The non-ionizing waves are generally unsuccessful in damaging the DNA and body cells and are much safer than the ionizing waves.
