常见错误

❌ 错误:The material is radioactive decay.
✓ 正确:The material decays radioactively.

错误用法中误将形容词 'radioactive' 与名词 'decay' 直接搭配,正确用法应使用副词 'radioactively' 修饰动词 'decays',描述衰变的方式。

❌ 错误:They tested the water with radioactive.
✓ 正确:They tested the water for radioactive contamination.

错误用法中 'with radioactive' 不完整且语法错误,正确用法应使用名词短语 'radioactive contamination' 或类似结构,表示测试的目的。

近义词辨析

radiatively

radiatively 更侧重于通过辐射(如热或光)传递能量,而 radioactively 特指通过放射性衰变释放辐射,常用于核或原子层面。

Heat is transferred radiatively in space, whereas uranium decays radioactively over millennia.

nuclearly

nuclearly 是一个较少使用的词,可能指与原子核相关,但 radioactively 更具体地描述放射性过程,在标准英语中更常见和准确。

The reaction proceeds nuclearly in theory, but in practice, it is described as occurring radioactively due to emission.
