RADIO WAVES

RADIO WAVE RADIATION

• Longest wavelengths on EMS
• Lower frequencies
• 100GHz-10KHz
• Lowest energy

Radio waves are found at the end of the EMS. They have the longest wavelengths and the lowest frequencies of all types of waves in the EMS. Radio waves also have lower energy than waves with higher frequencies.

Cellphones send low energy radio waves to towers called cells. The cells strengthen the signal and send it to other cells or the phone of the recipient.

HEALTH RISKS

1. There isn't any info confirming that there is a risk

2. X-Rays are an example of radiation, but so is the light that comes from the sun and the heat that is constantly coming off our bodies. Radio frequency (RF) radiation is at the low-energy and of the EM spectrum and is a type of non-ionizing radiation. If RF radiation is absorbed in large amounts by materials containing water, such as food, fluids, & body tissues, it can produce heat. This can lead to burns and tissue damage. Ex- of high-energy radiation include x-Rays. It, as well as some higher energy UV radiation, are called ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. This can damage the DNA inside of cells, which can result in cancer. People can exposed to RF radiation from natural sources.

Which include: outer space and the sun, the sky-including lightning strikes, the earth itself-most radiation from the earth is infrared, but a tiny fraction is RF.
