I am more concerned with putting a cellphone next to my head than I am with putting my head into an X-Ray radiation computerized tomography (CT) brain scanner.

In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or sequence, of the amino-acid residues along the polypeptide chains. This was first determined by [Frederick] Sanger using chemical techniques for the protein insulin, and has since been elucidated for a number of peptides and, in part, for one or two other small proteins. The secondary structure is the type of folding, coiling or puckering adopted by the polypeptide chain: the a-helix structure and the pleated sheet are examples. Secondary structure has been assigned in broad outline to a number of librous proteins such as silk, keratin and collagen; but we are ignorant of the nature of the secondary structure of any globular protein. True, there is suggestive evidence, though as yet no proof, that a-helices occur in globular proteins, to an extent which is difficult to gauge quantitatively in any particular case. The tertiary structure is the way in which the folded or coiled polypeptide chains are disposed to form the protein molecule as a three-dimensional object, in space. The chemical and physical properties of a protein cannot be fully interpreted until all three levels of structure are understood, for these properties depend on the spatial relationships between the amino-acids, and these in turn depend on the tertiary and secondary structures as much as on the primary. Only X-ray diffraction methods seem capable, even in principle, of unravelling the tertiary and secondary structures. [Co-author with G. Bodo, H. M. Dintzis, R. G. Parrish, H. Wyckoff, and D. C.

It is well known to radiation researchers that multiple CT X-Ray radiation scans may lead to degraded health and possibly cancer.

It is prudent to treat for radiation sickness in the weeks following an X-Ray radiation computerized tomography (CT) scan.

It's a shame, when I'm at the checkout line, and the cashier holds up my bill to the light, in search for a ghost president, or slashing a yellow marker to see if counterfeit. Even in money we can't be trusted. Makes we wonder whats next, will the government make a marker to slash our hand, or an x-ray we will have to walk through, to check if we have a dishonest heart or corrupt spirit?

Or the woman in front of me in the security line who asked if they would put her cat, Dave, through the luggage X-ray machine because she wanted to see if he'd eaten a necklace.

The medical profession is addicted to the over use of biologically harmful CT X-Ray scans because they are so profitable.

People ask me where I got my x-ray powers. I inherited them from my parents in parental supervision. Erase the dots and your doubts if you think that I was 'raysed' alone.

You should not have a biologically harmful CT X-Ray scan unless you feel that your life depends upon it.

The x-ray of your skull shows a large, flobby mass floating inside. I have to consult my colleagues to be certain, but it looks like a long sausage snarled into a lump.

There's an urban myth, still popular in some quarters, that the Glock can't be detected by X-ray machines. The myth was spread by a Bruce Willis line in the 1990 movie Die Hard 2: "That punk pulled a Glock 7 on me. You know what that is? It's a porcelain gun, made in Germany. Doesn't show up on your airport X-ray machines." Every bit of the line was false: there was no such thing as a "Glock 7"; Glocks are made of polymer, not porcelain; it was made in Austria, not Germany; and they do show up on X-ray machines. But in a strange twist, the firestorm of controversy triggered by the false rumors may have helped goose publicity and aid Glock sales.

Borges's extreme architecture attempts to visualize the universe by assigning to every object real and unreal, now and yet to come, a code or sign, a corresponding figure within the Library. It seeks to render totality visible, to effect a total visibility and visuality. The Library of Babel is a view of the universe inside and out, an X-ray of the universe and universal X-ray, seen from within and without. It is a representation of everywhere: a perfect duplication of the universe. And of you: universal. An endless and eternal cinema, an imaginary archive that extends into the universe until it is indistinguishable from it, until you are indistinguishable from the universe.

After living an allergy free life, I developed seasonal allergies after having a CT X-Ray radiation scan of my lungs.

At the age of 49, I had been in the X-Ray radiation computerized tomography (CT) scanner for two brain scans, one nasal scan, and four lung scans.
