IPA: //ˌreɪdiˈlɪtɪk//
KK: /reɪdiəˈlɪtɪk/
Relating to the process of radiolysis, which is the chemical decomposition of materials due to radiation exposure.
The radiolytic effects on the material were studied to understand its stability under radiation.
Radiolytic → It is formed from "radio-" (from Latin *radius*, meaning ray) and "lytic" (from Greek *lytikos*, meaning capable of loosening or breaking down). The word refers to processes involving the breakdown of substances by radiation.
Think of 'rays' ('radio-') that can 'break down' ('lytic') materials, which helps you remember that 'radiolytic' relates to the breakdown caused by radiation.
