2. Description of x-ray
An X-ray machine produces a controlled beam of radiation, which is used to create an image of the inside of your body
electromagnetic waves with wavelengths in the range of to 10 nanometers
frequencies in the range 30 petahertz to 30 exahertz
X-ray travel at meters per second

3. The uses of an x-ray
they can penetrate less dense matter such as skin and body tissue
they are commonly used in hospitals to produce photographs of bones which can be checked for breaks or fractures
chest x-rays can spot pneumonia
Mammograms use x-rays to look for breast cancer

4. Source of x-rays The sun
Any naturally occurring radioactive material (ie. uranium) can cause X-Ray emission from Compton scattering

5. Benefits and hazards of an x-ray
Risks from exposure to ionizing radiation include: a small increase in the possibility that a person exposed to X-rays will develop cancer later in life
X-rays aren't safe because radiation exposure can cause cell mutations that may lead to cancer

6. The limits of an x-ray
X-rays has a limit the longer you stay in front of an x-ray the higher your chances to get cancer
