X is for X-rays in ABC W

I have a strong feeling that I will not be alone with this choice - but no matter: This is my version. According to Wikipedia:

An X-ray (or Röntgen ray) is a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015Hz to 30×1018Hz). They are longer than Gamma rays but shorter than UV rays. X-rays are primarily used for diagnostic radiography and crystallography. X-rays are a form of ionizing radiation and as such can be dangerous. In many languages it is called Röntgen radiation after one of the first investigators of the X-rays, Wilhelm Conrad Röntgen.
Thus, in Norway X-rays are always called røntgenstråler and the pictures røntgenbilder. Ususally all this is shortened to rtg. Most people come into contact with X-ray when they are checked for broken bones or other medical defects, or when they are doing their dental check-ups. It is not as easy as one should imagine to diagnose correctly X-ray pictures, and as with all kinds of photography, many demands must be met to achieve the best possible result.I will show you an example of what a typical dental X-ray picture of a grown-up person looks like. The picture was taken in the mid 90s, so hopefully the situation for the same age group is better today.This is a so-called "bite-wing" - typical for routine examinations. I have not included all that one can read out of this (there would not be room), but have included some of the tissues and various dental restorative materials. The reason they look different is that they absorb different amounts of radiation, leading to less exposure of the film at this point. This is the basis for all X-ray diagnosis. A cavity would be totally black against the grey of the tooth-substance. However - you will not see this in this picture because the patient did not have caries! Nowadays, most x-ray pictures are digital, leading to both less exposure for patient and personnel, and less chemicals to the environment. A win-win situation.

Tenkte meg at du hadde dette valget;) Ja, jeg tenkte på det selv faktisk og leitet huset rundte etter noen gamle røntgenbilder. Fant dem ikke i farten og tok en kriseløsning.
Bra og informativ post, Rune:)

Denise said...

Wow! How fascinating!I love how much info we all share each Wednesday!

reader Wil said...

Another clever solution to the X-problem! I couldn't find an X word other than x-ray, xenophobia and xylophone, but I couldn't picture them. You are clever without doubt.

Made my registration but still don´t know any x word.
Tried to use old chinese emperors but had no time to scan pictures og them (only 4 possible)
Have to go to my x-file and have a look there

Spennede lesning ja..., noe kjent, men noe ukjent også i grunn. En lærer av denne bloggingen sier jeg til familien, når de klager over tastauret som klaprer :-)

Men du..., faktisk forunderlig mange med hel proteser eller store broer synes jeg. Ved gastroscopi undersøkelse hos må nok alle tennene hos pasienten sitte fast... det er da vi må spørre om de har proteser... og noen ganger kan det være ganske kinki i grunn, for en skal jo ikke anta etter alder osv...

Husker i alle fall en eldre mann, og for å prøve gripe saken litt lett an suprte jeg forsiktig;
"Har du dine egne tenner...?"
Svaret kom kjapt tilbake "JA! Du tror vel ikke jeg har tatt nabon sine??"...

Etter det har tannproteser blitt "vanlig" i vokabulæret mitt...

klem herfra.

Max-e said...

This brings back memories of the many xrays I had with my by pass operation, and also reminds me if a trip to the dentist I keep putting off

Dragonstar said...

Michele (Rocky Mtn.Girl) said...

Cool.... loving the lesson here on X- rays!... Great post. I read it all and it will be stuck in my head forever!

John said...

Meget flott og lærerik X post Rune.
Skulle man bruke disse frekvensene til radiosending så hadde rekkevidden blir veeeeldig kort.
Very well done.

GAWO said...

Har du startet med odontoligiutdannelse pr. nett? ja, hvorfor ikke.
Godt valg for X, Ikke så lett å finne på noe, og jeg som har ferie og greier og bare kjører på 2 hjul lar det hele passere. Men jeg koser meg med ditt valg.

Jerez said...

Ouch!
I have an almost perfect mouth, but almost isn't perfect, one tooth missing causes all kinds of problems.

I'm glad someone thought of creative x words..

I don't like going to the dentist! But then, who does? lol

Hyde DP said...

Paulie said...

I expected to see xray for this post but not a teeth one! Good info.

BTW, my W word is a brand name so maybe they aren't world wide?

mylittlephotonook said...

Vilket smart "X".Där fick du till det Rune!

Paulie said...

You are correct . . . I meant X in my comment. . . my allergies are getting the best of me and I am not fully "awake" when I posted W. . . thanks for noticing.

AphotoAday said...

Oh, you just had to go and remind me about the dentist, didn't you...
(on a dental chart I believe an x indicates a missing tooth)
Hope you are having a great x day...

Daryl said...

Oh .. clever .. this is the second x-ray but the first of teeth! How fun!

As to the Xylophone .. see there to the musician's left? There's a case he puts it in and rolls it along!

Gary said...

Why didn't I think of that. Well, maybe next time.

VP said...

Ughh - it's been a bad week at the dentist's for me so far, so those X rays are a familiar sight to me already!

becky voyles said...

WOW! Very informative. How did you get the dental photo. Were or are you a dentist? Neat idea.

Aileni said...

Are these part of an orbital, RuneE ?
They have the symetrical look.
They make a good 'X' don't they.

Andrea said...

I have had many x-rays taken lately but I did not have one on hand to take a picture of. I was blank for X so I passed. I did post an awesome spiderweb I took at night though.

nonizamboni said...

Very clever post--interesting choice! Thanks for sharing. Happy Wednesday.

Daniel J Santos said...

excellent idea for the X post, well done.

Louis la Vache said...

eXcellent choice, Runee!

"Louis" is buried deeper than his cowbell in a work project for the next several weeks. He will stop and visit, but may not stay long enough to 'sign the guest registry'.

Diana said...
