Medicine, Skeletons, Radiation
Did you know that right now, at this very moment, there is a skeleton inside of you? That's right, an entire skeleton! Quite the bold claim, but with the invention of the X-ray in 1895, medical professionals have provided irrefutable proof of these spectacular skeletons in action. Proper precautions need to be taken when working with these powerful machines, as prolonged exposure can lead to radiation sickness. Today, X-rays are operated by trained professionals in controlled environments, and injury due to X-ray photons are rare. The X-ray has proven to be an invaluable asset to both medical science, and any book or poster with every letter of the alphabet.
