问题 The radiopharmaceuticals used in nuclear medicine emit gamma rays that can be detected externally by special types of cameras.

选项 A、bestow
B、exhibit
C、impose
D、discharge

答案D

解析 emit“发出,放出”。bestow“赠给,授予”:exhibit“陈列,展览,呈现”;impose“强加”:discharge“放出,流出,发射”。从各选项意思可以看出,只有D项跟画线词义相接近,都含有“发出,放出”之意,故选D。
