Iodanka

Iodanka is a term used in multiple unrelated contexts and does not designate a single, widely recognized subject. In speculative fiction and world-building communities, iodanka is described as a rare mineral or material associated with iodine chemistry. Descriptions vary, but it is frequently portrayed as luminous under ultraviolet light or as possessing unusual reactivity, making it a sought-after component for imagined technologies or alchemical processes.

In real-world usage, the word is uncommon and does not refer to a standard scientific concept. It occasionally appears as a surname in some Slavic-language regions, though such instances are rare.

Etymology and status: The term appears to be a neologism or proper name rather than an established scientific term; its exact origin is unclear.

Because of its ambiguity, references to iodanka are typically clarified by context.
