Cell phones cause a cancer risk Essay Sample

Cell phones cause a cancer risk Essay Sample The 1990s were the years when people started using mobile phones. The number of active users was growing with every year. People spent more and more time holding a phone in hands or near the ear. Adults and children spend a lot of time next to the cell devices today that make the whole picture of using various gadgets completely different from the one that we could observe ten years ago. The concern about the fact that cell phones cause cancer appeared because mobile devices produce energy that is called radio-frequency signal or RF. People feel worried about the future of their health the future life of their kids as it’s hard to imagine a family that doesn’t have a phone. Is there any risk of having a brain tumor because of using the gadget? Myths and legends make people look for scientific proves that give the right answer to this question. Do mobile phones cause cancer? Smartphones work the same way as all the other mobile devices that you can find in any store. As we all know, there are various types of signals like microwaves, FM waves or X-rays. Every type of signal has its strength and the level of influence on the human’s body. The signals produced by a phone are similar to the FM signals that are called as non-ionizing emission. It means they are not so powerful to change the DNA of a cell and cause disease because of it. We know that UV waves and X-rays can change the DNA parts and cause serious problems with health. They belong to an opposite group of waves that are called ionizing emission. If we take a closer look at the work of microwaves, we will notice that these waves can heat the food that we put inside of it. If we use the RF signals at a high level for a long time, it will produce the same effect on the cells that are located close to the phone. Harmful effects of mobile phones Every cell phone has an antenna that is hidden inside the body of the gadget. The level of emission is the highest inside the device and it falls down together with the distance. The close and longer we hold the gadgets near head the more we are exposed to the RF emission. Of course, there are some things that influence the level of emission perceived by human cells such as: Period of time; Miles to the device; Miles to the closest tower; Number of active users per a tower; Model of the device. The conclusion here is easy for understanding. There are reliable cell phone radiation facts today. The more and the closer the phone is near our heads the more radiation our cells receive. We won’t become hot like a sausage in the microwave, but we will influence the work of the cells anyhow. The dangers of cell phones There’s a special measure that can calculate the amount of radiation received by the cells of the human body. It’s called the specific absorption rate or SAR. Cell phone radiation levels differ from model to model. All the manufacturers are obliged to inform their buyers about the highest SAR level produced by their gadgets. The limit is 1,6 W/kg for the gadgets sold on the territory of the US. It’s dangerous to buy a device that doesn’t have this information. Considering these figures as a norm is not a good idea. Every manufacturer states the maximum limit that can be reached in specific situations. Cell phones and cancer are the terms as are considered to be synonyms for some people. There’s no urgent need to panic without a thorough investigation of what the real influence of devices is. Cell phone radiation effects on human body All the experiments that were conducted in laboratories proved that cell phone radiation effects are neutral. Animals didn’t suffer from any kind of tumor in any part of the body after active absorption of RF emission. There are no proofs besides the rumors that RF emission can hurt the cells of a human body. Of course, no one will ever experiment with humans to check if it’s true for 100%, but the supposition is based on the lab experiment with animals. Can you get cancer from cell phone?
