In Addition Mobile phones send and receive radio waves, which they then changes into sound. Above a certain level, radio waves will heat human tissues, but all mobile phones sold in the UK should meet international guidelines set to make sure this does not happen.

Ionizing and non-Ionizing radiation
Ionizing radiation is energetic or that have the potential to an or through atomic interactions. It is a function of the energy of the individual particles or waves, and not a function of the number of particles or waves present. A large flood of particles or waves will not cause ionization if the individual particles or waves are not energetic enough. These ionizations, if enough occur, can be destructive to biological organisms, and can cause in individual cells. Extensive doses of ionizing radiation have been shown to have a effect to future generations of the individual receiving the dose. Examples of ionizing radiation are energetic , , and energetic (UV and above). The amount of energy required to ionize an atom or molecule may widely vary. and will ionize almost any molecule or atom; Far , near ultraviolet and are ionizing to very few molecules; and are .
is so ubiquitous that will often react nearly spontaneously unless protected by materials that block the visible spectrum. Examples include photographic film and some molecules involved in .
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 that does not carry enough per to atoms or molecules — that is, to completely remove an from an or .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. Nevertheless, different biological effects are observed for different types of non-ionizing radiation.
, , , , , low frequency RF and static fields are all examples of non-ionizing radiation. Visible and near ultraviolet may induce , ionize some molecules or accelerate , such as photochemical of varnishes or the breakdown of flavoring compounds in beer to produce the 'lightstruck flavor’. The light from the that reaches the earth is largely composed of non-ionizing radiation, with the notable exception of some rays. However, most ionizing radiation is filtered out by the atmosphere (see ). Static fields do not radiate.
It is known that microwaves do cause harm and could cause effects such as fatigue, headache, sleep disorders etc…: this might be because the person might be exploited to microwave radiation a lot or have been using their mobile phones to much, there is no clear evidence for this just yet as scientists are still researching this subject.
Do Mobile phones cause tumors?
“Long-term users of mobile phones are significantly more likely to develop a certain type of brain tumor on the side of the head” researchers believe that long-term users of 10 years of using a mobile phone are 40% more likely to develop nervous system tumors called gliomas near to where they hold their phones.

Tumours:
The causes of brain tumours are still mostly a mystery. The two known risks are high doses of ionising radiation to the head (scarily, once used to treat the simple fungal infection, ringworm, of the scalp, as well as other cancers); and certain genetic conditions, such as neurofibromatosis and tuberous sclerosis. But these account for only a small number of cases.
There have been some reports in the media about the risk from mobile phones. But these fears have been shown to be
Worries about ultrasound scans during pregnancy and use of other electrical devices have also proved unfounded. There may be links to certain occupations, possibly due to exposure to chemical or physical cancer-causing agents.
Symptoms
Brain tumors can cause almost any symptom, depending on which part of the brain is affected. Brain tumors can cause almost any symptom, depending on which part of the brain is affected. But, typically, one or two symptoms first draw attention to the problem.
The two most common early warning signs are caused by an increase in pressure in the skull as the tumor grows (called raised intracranial pressure): a headache, which is usually worse in the morning, on coughing or exertion, and nausea.
Although these can be everyday sorts of problems for everyone, they should be checked out by your doctor if they persist.
Raised intracranial pressure also causes:
- fits or faints
- visual disturbances
- confusion
Other symptoms depend on which part of the brain is affected. Common ones include:
- numbness or weakness on one side of the body
- loss of coordination or balance
- changes in personality
- loss of intellect
- changes in senses, such as smell
- problems with speech, writing or drawing
The diagnosis is usually confirmed using a brain scan.
Are Children at more risk then adults?
Many scientist and articles debate about children having more risk from mobile phone radiation this might be because they have not developed properly yet, things inside and outside their body is still developing and needs time to grow for example their brain, in addition because their cranium are thinner than those of adults, little children can absorb more radiation than adults, if lots of radiation from the mobile to a Childs brain is a substantial amount which is enough to cause a tumor then the child will have a real high risk rate of having side effects or even having a tumor.
Advice About Using Your Mobile Phones:
- keep your calls short;
-
consider relative Specific Absorption Rate (SAR) values when buying a new phone. SAR is a measure of how much radio wave energy your body receives from any particular model of mobile phone. All phones sold in the UK have to be tested to ensure they produce SAR values below 2 watts per kilogram. You can compare the SAR values of mobile phones on the UK market before you buy at
- Experts suggest that mobile phone users can take a number of precautions to reduce any possible health risks.
- Almost all agree that the best step is to keep mobile phone conversations short and to a minimum.
- Many believe that so-called hands free kits reduce the risks by cutting the amount of electromagnetic radiation entering the brain.
- They also recommend that users buy phones with external aerials so that it is as far away from the head as possible when in use.
- Similarly, it is believed that phones with a long talk time are more efficient and produce less powerful emissions.
- Users are also advised against buying handsets with a high "SAR" value, which means it emits more radiation.
(Some Information Taken From And From )
There are articles for mobile phones that are saying they are safe for example the daily telegraph, “Mobile phones appear to be safe, but more research is needed to be certain they pose no health risks, scientists advising the Government said.” The group, chaired by Anthony Swerdlow, claims that they examined all the available evidence from research into the hazards of mobile phones and base stations over the last three years but yet they believe mobile phones do not have much risk. In addition the Stewart report said there was no clear evidence that mobile phones was harmfull to your health, but accepted they may be some biological effects.
I agree with this article from the telegraph, I am for mobile phones yet I still believe that there are biological effects like the telegraph article has just said, this is because there are some occasions of events that people have suffered from fatigue or something in this relevance but its still not clear if mobile phones cause this.
Conclusion:
Mobile phones are very useful, and are used in everyday life and have been growing in number everyday of people having one; mobile phones can save lives in emergencies or in general be for good use such as internet. We should not disallow mobile phones as there is no clear evidence of that mobile phones cause LOTS of harm. On the other hand we should find more ways into researching any evidence of slow-rising effects of the mobile phones might do. In addition the use of mobile phones near children should be kept at a low-level but unfortunately this really be unlikely to happen mostly as kids as low aged of 8 years already own a mobile phone of their own the ALARA principle should be used.
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.
