X rays are an electromagnetic wave, they have short wavelengths, high energy and they cause ionisation. This kills and mutates cells which causes cancer. When switching on an X ray, the radiographer stands behind a screen to reduce this radiation.

- The film is white.

- X rays can pass through the casette and turn the film black.

- Bones can absorb X rays - X rays can't pass through them so the film stays…
