Sharpie always rises to the surface

"Radiography" is x-ray imaging.

I wonder if he means Rapidograph...    

I took it as a marker used for annotating X-Ray photo films.

I should also mention an alternative to the standard black Sharpies (which are really dark purple) and run when exposed to many paint solvents.  There is also a "red label" Sharpie industrial marker. It seems to be more solvent resistant. The stated color is black but it is a really dark blue.  You guys might want to give it a try.  I just used it the other day to blacken some metal parts.

On related note, there are no films in radiology departments for the most part. Digital imaging has been standard for years now. Marks are digital if used, measurements easily made. So no pens or markers used. They use tattoos for radiation treatment targets, but that's about it. FWIW.

Yes thats it. To be honest I thought it was a pen used for marking X-rays. Don't usually bother with glasses for reading small print on marker pens so thanks

So we were all partially correct.

Rapidograph is a type of a technical pen. Some are filled with India ink.  I sometimes use very fine type of marker for accenting panel or door lines, or for some precision detail-painting.

The ones I use are Sakura Micron markers. https://sakuraofamerica.com/pen-archival#  Not sure if those are used for Gundam stuff.
