I was thinking about studying radiology, do you know anything about it?
Yes I do! It's the science of medical imaging. It's used to help diagnose people for things inside their bodies. It's very effective and a medical breakthrough.
That sounds complicated, is there a long history behind the science of radiology?
Yes! There are a variety of techniques used, like x-rays, ultrasound, computed tomography. The person who originally studied x-rays got very sick because they didn't realized that they can hurt you
That's really unfortunate for them! Who was that person that studied x-rays way back then?
x-radiation was discovered by a German scientist named Wilhelm Röntge. But I believe it was a lady who was first to use it for medical purposes. 
Oh okay, can you tell me more about the life of Wilhelm Röntge if possible?
I don't know much about him to be honest. He did discover that x-ray wavelengths were shorter than the UV waves, but longer than gamma rays. It's all very complicated for me. 
That does sound quite complicated. Do you know anything else about gamma rays? Those sound quite neat.
I do! They are made of photons in the largest range of photon energy! It's quite spectacular.
