With one in five Americans developing skin cancer, childhood education about sun safety is a vital step toward reducing risk and improving public health. Overexposure to the sun's ultraviolet (UV) rays seriously threatens human health. Besides the immediate effect of sunburn, over time excess UV radiation can cause skin cancer, eye damage, immune system suppression, and premature aging. About 23 percent of lifetime sun exposure occurs before the age of 18. Learning about sun safety and dangers of sunbeds is the key to reducing the risk of future health problems.
Radiation is all around us, every minute of every day. Some radiation is essential to life, such as heat and light from the sun. We could not exist without it. Some radiation informs and entertains us, through video signals and sounds from television sets and radios. As used in medicine, radiation helps us diagnose and treat diseases and save lives. Yet it can also pose serious risks.
