Exposure to magnetic force fields isn't something new to us human beings. However, throughout the twentieth century, environmental exposure to unreal magnetic force fields has been steady increasing as growing electricity demand, ever-advancing technologies and changes in social behavior have created a lot of and a lot of artificial sources. Most are exposed to a mixture of weak electrical and magnetic fields, at house and at work, from the time of discovery and transmission of electricity, domestic appliances and industrial instrumentality, to telecommunications and broadcasting.

As a function of the frequency (or wavelength), the EM waves are typically classified into one among the 2 radioactive categories: (i) magnetic force fields or non-ionizing radiations: Low-level radiation that is usually perceived as harmless to humans; and (ii) magnetic force radiations or radiation, i.e., high-level radiation that has the potential for cellular level damage like irreversible damage to the molecular structure of the DNA.

The ionizing radiations have a frequency high enough to provide the ionization of molecules and atoms through the breaking of the chemical bonds of the molecules. Few examples for the waves under discussion here are the X-rays and radiations created by radioactive sources.

Fig.1 This image shows effect of ionizing radiation on DNA cells.

The non-ionizing radiations (NIR) correspond to those waves of the spectrum whose energy is simply too low to interrupt the atomic bonds. Among these radiations are the ultraviolet and visual lightweight, the infrared radiation, the radio frequency and microwave emissions, the extraordinarily low frequency fields and therefore the static magnetic and electrical fields. The NIR, even at terribly high intensity, cannot turn out ionization in a very biological system. yet, these radiations are proved to provide alternative biological effects, like heating, alteration of some chemical reactions or induction of electrical currents on tissues and cells.

The topic of EM (Electromagnetic) radiation, together with its impact on human health and therefore the setting is encircled by loads of confusion. it's simple to believe pseudo-scientific rumours once there's no approach, or will, to check the knowledge. you may have detected that if phone mast is much away, you're not exposed to radiation or that you just shouldn’t use a kitchen appliance as a result of it makes your food radioactive or mobile towers have unhealthy impact on health of birds. Let’s discover the reality behind a couple of common myths regarding radiation.

Myth 01: Reason for dwindling numbers of birds are mobile tower radiations.

Truth 01: There are studies to recommend the claim is true however at a similar time there are alternative reasons that contribute to dwindling numbers of birds like pesticides, surround destruction, etc. There are instances of birds nesting on the mobile towers that recommend otherwise of the impact of mobile towers.

Myth 02: there's no safe dose of radiation.

Truth 02: Radiation happens everyplace in our everyday lives, therefore it might be not possible to be negatively full of little doses of it. There are differing kinds of radiation and it's emitted from each natural and unreal sources. Low levels of radiation won’t influence you like a shot however they'll increase your risk of obtaining unwell after you are exposed for a protracted time, e.g. employing a portable by pressing it against your ear, for a couple of hours on a daily basis, for a couple of years.

Myth 03: Microwaved food is radioactive.

 Truth 03: this can be a typical story caused by an absence of data regarding radiation. Some individuals suppose that microwaves will create food radioactive as a result of they’ve caught up emission and magnetic force waves. Microwave ovens shouldn't be used too typically thanks to the very fact they increase the doses of radiation we tend to get exposed to. If you're involved regarding the standard of your food, you ought to grasp that once heated in a very kitchen appliance, some nutritionary values are reduced.

Myth 04: Use a cell phone in a very vehicle as a result of the automotive being able to protect you from the radiation.

Truth 04: Most cars have metal roofs and there's loads of tinted glass, in order that they will act as a Michael Faraday cage. Radiation is treed within an automotive via The Michael Faraday impact (if you don’t have windows opened or a properly mounted automotive antenna). The RF radiation is targeted that the microwaves penetrate the flesh at higher EM intensities, it doesn’t escape through the metal body of a vehicle. after you try and create a decision within the automotive with all the windows closed, the phone signal is weak, that the portable will increase its power to search out the closest transmitter. It will increase the SAR (Specific Absorption Rate) value of the phone, therefore it's not safer to assume and use a mobile phone in vehicle or your own car.

Myth 05: If mobile phone towers are at far distance, you're less exposed to radiation whereas employing a phone.

Truth 05: If mobile phone towers are at far distance from your home, they still will influence you however in a very completely different approach. Simply because we tend to not see one thing operating, doesn’t mean it isn’t. Your exposure to radiation depends each on the space from the mobile phone tower and therefore the strength of the phone signal. Whereas a network’s signal is low, a cell phone mechanically sends and receives a lot of powerful signals in order that it will reach the nearest cell tower. If it's still not in the reaching limits, cell phone users are exposed to a lot of radiation from their device. Your phone must work on the next power to stay the communication with the mobile phone base station. It’s higher risk to speak on a phone with an occasionally low signal on your phone. After you grasp there are not any mobile phone towers within the neck of the woods, expect a far better signal before creating calls.
