against radiation / protects from radiation

Etymology
Etymology Information

'anti-radiation' originates from the Greek prefix 'anti-' meaning 'against' combined with the English noun 'radiation' (from Latin roots related to 'ray' or 'to beam').

Historical Evolution

'anti-' comes from Greek 'ἀντί' (anti) meaning 'opposed to' or 'against'; 'radiation' comes via Latin 'radiare'/'radius' (ray) and later French/Latin developments into Middle English 'radiation' and modern English 'radiation'. The compound 'anti-radiation' formed in modern English usage to describe opposition to or protection from radiation.

Meaning Changes

Initially the parts meant 'against' + 'ray/beam'; over time the compound came to mean 'against or protective of radiation' in both technical and general contexts, maintaining the original components' senses but used specifically for protection or countermeasures.
