Resistance
"our planet is a natural source of what the uxzu called _iliadium_, with unusually high fractions of its stable isotopes. the radiation interferes badly with wanesh technology, so they only come down rarely."

Are there isotopes of tungsten?" "it's the same as everything else in the system, sir. the sample they provided is just wolframite embedded in a quartz matrix.
The Diplomatic Affair
isotopes?" "the same ones. what about the comm logs? maybe we can decrypt them." despite barry's initial optimism, there was nothing to decrypt.

Hell just yesterday he had been sitting there in his eighth period chemistry class; lost in his own daydreams rather than learning about ions and isotopes, when out of the blue he felt himself get instantly hard and spontaneously creaming in his khakis.
Log Reports
Compounds --28.1% silica-based borides --14.2% hydrocarbons --12.7% organic compounds and proteins (including enzymes, hormones, nucleic acids, and unrecognized lipid structures) --4.2% theta-level heavy metals --3.8% omega-level broad spectrum isotopes
Book Two: Lost In The Mist *FULL LENGTH*
Still active, runnin' off heavy isotope temperature differential. it's thinkin' right now, and gots no inputs." "er... nod. what am i going to do with this?"
WOLF
The radiation it gave off was a result of isotopes used in its manufacture to make it last in the immune system of a person who's body was hyperactively healing itself. it was tailor made for shifters.
