Introducing X-radiation

John Holroyd introduces what atoms and x-rays are, and includes key definitions.

The video above will refresh your knowledge of what X-radiation is and how it is produced. This will ensure you have a solid understanding before we move on to the hazards and health effects of radiation.

The video first looks at how X-rays are produced. The workings of an X-ray tube are described as well as the two types of effects that create X-rays. The X-ray energy spectrum is introduced and the process of filtration to remove low-energy X-radiation is explained. The concept of the primary X-ray beam and scattered X-radiation is also covered in this step.
