x-Ray

Look, I am running out of nice things to say about Miami, so I snapped this photo, which is from a hospital in Miami... to tell you about what you may not know, that "they" sometimes give you a dose of this when you least expect it. What am I talking about? X Ray (or x-Ray)... the stuff that comes out of Superman's eyes when he looks at you:

X radiation (composed of X Rays) is a form of electromagnetic radiation. x-Rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 raised to power 16th Hz to 3×10 raised to 19th power Hz) and energies in the range 100 eV to 100 keV. When they want to look inside you to see your internal structure, they zap you with somewhere between 10 to 120 keV. Ouch! I have no idea how they can decide how many keV to zap you with. If I were to be laying on that table, I would like to know... and I would wear some lead underwear too! Wonder if they'll let me do that!

This is a state of the art x-Ray unit for medical diagnostic service. It looks very expensive and yes, it's all digital now... No more messy films to deal with. No, it's not for me, thankfully!
