What Are The Possible Risks Of Using A Mobile Phone?

What are the possible risks?

There are fears that the electromagnetic radiation emitted from mobile phone handsets may harm health.

In particular, there have been claims that it could affect the body's cells, brain or immune system and increase the risk of developing a range of diseases from cancer to Alzheimer's.

While there is no evidence to back up these fears, laboratory tests on mice have shown that radiation from mobile phones can have an adverse effect on their overall health.

It is still not clear whether those findings can be applied directly to humans.

A study by scientists in Finland, published in 2002, suggested that the electromagnetic radiation did affect human brain tissue.

mutating effect to future generations of the individual receiving the dose. Examples of ionizing radiation are energetic Beta particles, neutrons, alpha particles and energetic photons (UV and above). The amount of energy required to ionize an atom or molecule may widely vary. X-rays and gamma rays will ionize almost any molecule or atom; Far ultraviolet, near ultraviolet and visible light are ionizing to very few molecules; microwaves and radio waves are non-ionizing radiation.

Visible light is so ubiquitous that molecules that are ionized by it will often react nearly spontaneously unless protected by materials that block the visible spectrum. Examples include photographic film and some molecules involved in photosynthesis.

Ionizing radiation has many practical uses in medicine, research, construction, etc. It also presents a health hazard to humans if used improperly. Both aspects are discussed below.

Non-ionizing radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules — that is, to completely remove an electron from an atom or molecule.[1]Instead of producing charged ions when passing through matter, the electromagnetic radiation has sufficient energy only for excitation, the movement of an electron to a higher energy state.

Conclusion

It is excellent that research has already begun on mobile phones of they cause harm or not, this perhaps will catch the publics attention and will make them think twice about there using their phones, and maybe follow the ALARA principle and will be safety precautious.

Furthermore maybe the manufacturing of the mobile the measurement of the radiation level from the phone should be put a label during selling or something between this region.

  1. Mutagenesis: The Effect of Radiation on Radish Seeds.

    Statistical data for plant root length at various radiation dosages Our observations of radiation effects on plant root length also indicate that length decreased as the dosage of radiation to which the seeds were exposed increased. This can be seen by comparing the average and standard deviation of the control, unexposed seeds (25.11 � 18.51)

    It makes gamma radiation in all kinds of ways. Similarities and Differences You may think that Radio Waves and X-Rays are nothing like X-Rays and Gamma Rays, but they are actually very similar. They are all produced in very different ways and we detect them in different ways- but they are all basically the same as they are all merely masses of photons.

    It is also why they are shiny. These free electrons oscillate together when light wave shine on it. Then radiate electromagnetically, this radiation from the oscillating electrons is the reflected light. In this situation, little of the incoming radiant energy is absorbed, it is just reradiated means it is reflected.

    Cancer is caused by genetic damage that happens inside an individual cell. This damage can be cause by the microwaves given off while you are on a mobile phone. These cells then divide at an accelerated rate, causing the tumor.

    Are mobile Phones Dangerous

    doing an experiment on radiation from mobile phones, they had 1000 phones and placed them on an egg to see if they could raise the temperature of the egg. In short nothing happened to the egg. This is why I do not think that mobile phones are dangerous.

  1. Gamma Rays

    Uses: UV light produces vitamins (in particular Vitamin D) in the skin and causes sun-tans. Note, though, that UV light is harmful even in modestly large doses. The shorter the wavelength the more dangerous the UV light is. It is used in bacteriology to kill some cells. Comments: UV light was found shortly after infrared (early 1800s).
