Few people set out to become x-ray experts. Not many children dream of becoming the next Wilhelm Rontgen. But life moves in unexpected directions. Whether you are a security professional, doctor, or physicist, x-rays impact your life. So we put together an x-ray guide with nearly 20 resources to get you up-to-speed on this important topic.
Our mission is to design and manufacture the world’s best x-ray security scanners. And this x-ray guide is tailored to those goals. But this resource also includes other x-ray uses, including how NASA uses the tool to study outer space. Read on, explore the amazing world of x-rays, and contact us whenever you need to purchase an x-ray unit.
HOW X-RAYS WORK
- X-ray (Wikipedia): Covers range of topics including the nature, production and uses of x-rays, and units of measure and exposure.
- Radiography (Wikipedia): Focuses on medical x-rays for seeing into the human body.
- What are x-rays? (LiveScience): Explains how x-rays are a form of electromagnetic radiation (EM) and shows where they fall on the EM spectrum.
- How x-rays see through your skin (YouTube): 5-minute video explaining x-ray scanner mechanics.
- Critical moments in x-ray history You Need To Know (Astrophysics, Inc.): Our handy x-ray history timeline.
