"exposure" can mean various things, & usually the meaning is not what 照
射 means.
https://ahdictionary.com/word/search.html?q=exposure
------------
None of the senses of "exposure" listed in the above definition is 
relevant to an example of usage such as this:
放射線は転移した癌細胞を破壊するために、通常腹部と胸部と頸部のリンパ節に照射され
る。
"Radiation is usually beamed to the lymph nodes in the abdomen, chest, 
and neck to try to destroy cancer cells that have spread."
------------
Consider this example:
放射線治療Q&A - JROSG-Japanese Radiation Oncology Study Group
いろいろな種類の放射線(X線・ガンマ線・電子線・陽子線・重粒子線)が、いろいろな方
法で照射されます。
This is saying that the radiation (or "rays") are *beamed* (or 
"radiated"), not that the radiation is "exposed". 
(It's the *cancer cells* that are exposed (to the radiation).)
