Origin
Sound + meaning六书liùshū
形声xíngshēngMost characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.
This origin belongs to the traditional form 鐳; 镭 is its simplified writing.
The traditional form 鐳 has 金 (metal) beside 雷, which gives the sound; the simplified 镭 is a later abbreviation.
