Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: radio- comb. form², halo n.

Etymology: < radio- comb. form² + halo n., after German Radiohalo (H. Hirschi 1920, in Vierteljahrsschrift der Naturforsch. Ges. in Zürich 65 221).

1971 Science 20 Aug. 728/1 A new type of composite radiohalo has been found with rings attributable both to the ²¹⁸Po decay sequence and to ²¹²Po and possibly ²¹²Bi.

1981 Amer. Mineralogist 66 360/2 The result..throws no light on whether atomic, as distinct from molecular, hydrogen causes the bleached, giant radiohaloes in Madagascan biotite.

2004 Current Sci. 87 666/2 The presence of radiohalos related to the daughters (²¹⁸Po, ²¹⁴Po, ²¹⁰Po) of ²²²Rn indicates that radon loss was not pervasive.
