常见错误

❌ 错误:The radiation is very strong today.
✓ 正确:The radiation level is very high today.

radiation 作为不可数名词,通常不直接与 strong 搭配;应使用 level 或 intensity 来描述其程度,如 high radiation level。

❌ 错误:I feel radiation from the microwave.
✓ 正确:I am concerned about radiation from the microwave.

radiation 通常不可被直接“感觉”,除非在特定语境如热辐射;更自然的表达是表达担忧或描述辐射的存在,如 concerned about radiation。

近义词辨析

emission

emission 泛指任何物质或能量的释放,如气体排放;而 radiation 特指能量以波或粒子的形式传播,常用于物理或医学领域。

Carbon emission contributes to pollution, while solar radiation provides energy.

irradiation

irradiation 强调辐射的过程或作用,如照射治疗;radiation 更侧重于辐射本身的现象或类型,两者在语境中可互换但侧重点不同。
