How safe are mobile phones

The conspiratorial bent is relevant — misconceptions about wireless technology have long perpetuated. The key message for kids is to cut their usage — the UK Government guidelines advise against mobile phones for unders.

Safe distance from cell phone radiation

Danish Study How the study was done: This cohort study, conducted in Denmark, linked billing information from more than , cell phone subscribers with brain tumor incidence data from the Danish Cancer Registry. The findings did suggest that the increase reported among the subset of heaviest regular users in the Interphone study could not be ruled out but was unlikely. The only consistently recognized biological effect of radiofrequency radiation in humans is heating. Elizabeth Ruffinengo, from Women in Europe for a Common Future, believes that as mobile phones represent a possible carcinogen there should be some safety recommendations. Mobile phones as well as wireless home phones send and receive voice and text messages via radio waves. Most of the scientists who are studying the health effects of cell phones are working in countries other than the United States, but that may change. Million Women Study How the study was done: This prospective cohort study conducted in the United Kingdom used data obtained from questionnaires that were completed by study participants. Last year, Sadetzki and her group found that heavy cell phone users had a 50 to 60 percent increased risk of a certain type of tumor. The Working Group indicated that, although the human studies were susceptible to bias , the findings could not be dismissed as reflecting bias alone, and that a causal interpretation could not be excluded. Mobile phone radiation is unable to penetrate far into your head. Like all the most enduring myths, fears over new technologies are built upon a tiny kernel of truth, hideously distorted.

By that date, the WTR had commissioned more than 50 original studies and reviewed many more. Neurologic effects are of particular concern in young persons since the brain is the primary exposed organ.

How safe are mobile phones

Many epidemiologic studies of cell phone use and brain cancer risk lack verifiable data about the total amount of cell phone use over time. However, researchers acknowledged that 'biases and errors in the study, limit the strength of the conclusion we can draw from these analyses and prevent a causal interpretation'. Elizabeth Ruffinengo, from Women in Europe for a Common Future, believes that as mobile phones represent a possible carcinogen there should be some safety recommendations. Not everyone agrees that mobile phones are a significant health risk, but reducing your exposure to the radiation they produce is definitely a good idea. And while radio frequency is non-ionising radiation — remember, it can't knock electrons off atoms, fiddle with genetic material and trigger tumour growth like ionising radiation can — studies still investigate possible links. The phone uses the antenna to receive radio waves, which it then changes into sound waves that a user can hear. But, Professor Croft said, "there were so many difficulties with that study. Investigators have also conducted analyses of incidence trends to determine whether the incidence of brain or other cancers has changed during the time that cell phone use increased dramatically. In addition, people who develop a brain tumor may have a tendency to recall cell phone use mostly on the same side of the head where their tumor was found, regardless of whether they actually used their phone on that side of the head a lot or only a little. In another paper last year , Professor Hardell found that; 'People who started mobile phone use before the age of 20 had a more than five-fold increase in glioma a tumour that develops from the glial cells in the brain or spine, and which accounts for over half of all primary brain tumours ', compared to those who had started using them later in life. An analysis of incidence data from Denmark, Finland, Norway, and Sweden for the period — similarly revealed no increase in age-adjusted incidence of brain tumors In our reporting for this story, we found not a single insurance company that would sell a product-liability policy that covered mobile phone radiation. The ability of microwave ovens to heat food is one example of this effect of radiofrequency radiation. Older studies evaluated radiofrequency radiation exposure from analog cell phones.

Researchers have carried out several types of epidemiologic studies in humans to investigate the possibility of a relationship between cell phone use and the risk of malignant cancerous brain tumors, such as gliomasas well as benign noncancerous tumors, such as acoustic neuroma tumors in the cells of the nerve responsible for hearing that are also known as vestibular schwannomasmeningiomas usually benign tumors in the membranes that cover and protect the brain and spinal cordand parotid gland tumors tumors in the salivary glands 3.

Today, cell phones use digital technology, which operates at a different frequency and a lower power level than analog phones. Bythe weight of scientific evidence linking cancer to smoking was overwhelming.

The phone uses the antenna to receive radio waves, which it then changes into sound waves that a user can hear.
