Scientists don’t know yet whether cell phones are bad for the brain.1.
In the experiment, the 47 participants may have looked a little strange. Each of them had two Samsung cell phones tied to his or her head—one on each ear.2. The phone on the right ear played a message for 50 minutes, but the participants couldn’t hear it because the sound was off. After 50 minutes with two phone attached to their heads, the participants were given PET scans. The PET scan is a way to take a three-dimensional picture of how the inside of the bodyworks.
The PET scan showed that the left side of each participant’s brain hadn’t changed from the way it was before the experiment.3. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that brain cells there were active even without the person hearing or talking anything. This activity, the scientists say, was probably touched off by radiation from the phone.
4. They release different amounts of radiation depending on whether a person is talking or listening, the type of phone, the number of people using phones nearby, and the distance to the nearest cell phone tower. All of these changes make it difficult to collect evidence about any health risks of cell phones, since exposure to radiation can vary.
So for those who don’t want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely.5.
A.The phone on the left ear was off.
B.So an experiment was done to attempt to find it out.
C.People should avoid having a long conversation by using cell phones.
D.Cell phones do not always give out the same amount of energy.
E.You can have short conversations, use a speakerphone to keep the phone away from your head.
F.The right side of the brain, however, had used more glucose, which provided fuel to brain cells.
G.From the PET scan the differences between the two sides of the brain were observed.
