What Are X-Rays And Gamma Rays?

There are many different types of radiation – from the light that comes from the sun to the heat that is constantly coming off our bodies. But when talking about radiation and cancer risk, it is often x-rays and gamma rays that people think about.

X-rays and gamma rays can come from natural sources, such as radon gas, radioactive elements in the earth, and cosmic rays that hit the earth from outer space. But this type of radiation can also be man-made. X-rays and gamma rays are created in power plants for nuclear energy, and are also used in smaller amounts for medical imaging tests, cancer treatment, food irradiation, and airport security scanners.

X-rays and gamma rays are both types of high energy (high frequency) electromagnetic radiation. They are packets of energy that have no charge or mass (weight). These packets of energy are known as photons. Because X-rays and gamma rays have the same properties and health effects, they are grouped together in this document.

There is one type of the most suitable material for radiation protection, which is tungsten alloy material; you could get more information from http://www.tungsten-alloy.com/en/alloy07.htm.
