Mobile phones and cordless phones emit a form of nonionizing electromagnetic radiation, radiation which may be absorbed by cells and tissues which come into close contact with the phone, e.g., the relative head and neck. The most conclusive evidence as to the dangers of cell phone and very similar radiation exposures come from studies on long-term exposure like this Swedish study. 300 percent increased risk for very long term usersThis new study reveals that people who used mobile phones and cordless phones for greater than a 12 months were at a 70 percent greater threat of brain cancer in comparison to those who used mobile phones and cordless cell phones for a yr or less.Whittle. He suggests that this may explain the apparent paradox. Different individuals may differ in their propensity for developing serious obstruction and also differ within their tendency to develop sudden clots. Dr. Whittle cautions that although this research shows that whites, on average, were much more likely to possess severe obstructions, many African Us citizens likewise have important obstructions. ‘Differences between racial groups are much smaller sized than differences among people within those groups.’ While research techniques and approaches increasingly emphasize studying different populations, Dr. Whittle and co-workers point out that a lot of modern scientific practice is certainly guided by studies done primarily in white men.
