<upd_detl>As already noted, from German Jod.  Minimally, the　度　doesn't seem to actually mean anything.  Not sure what an authoritative source would be on that, but google of 沃度　当て字 will turn up results.

Here's one:
http://s.jlogos.com/d001/705426670.html
沃素(ようそ)。▽「沃度」は当て字。(ドイツ)Ｊｏｄ

Interestingly, ヨウ素 and ヨード seem to be almost equal in popularity, both in kana and kanji forms.</upd_detl>

<upd_refs>I think this is our usual style with loanwords that have ateji

<upd_detl>Daijr and koj actually have separate ようど/沃度 and ヨード/沃度 entries but I think it's OK to ignore the hiragana reading. Daijs and meikyo only have katakana (and the 沃度 ateji).</upd_detl>
