α輻射的意思、翻譯和例句

是什麼意思

α輻射(Alpha Radiation)是一種由α粒子組成的輻射,α粒子是由兩個質子和兩個中子組成的氦核。這種輻射通常來自某些不穩定的重元素,如鈾和釷。α輻射的穿透能力較弱,通常只能穿透幾厘米的空氣,並且被紙張或皮膚表層所阻擋。雖然α輻射在外部環境中對人體的影響較小,但如果α源進入體內,則可能對健康造成嚴重危害。

依照不同程度的英文解釋

  1. A type of radiation made of particles.
  2. Particles that come from certain heavy elements.
  3. A kind of radiation that can be harmful if inside the body.
  4. Radiation that can be blocked by paper or skin.
  5. A type of radiation emitted by unstable heavy elements.
  6. Particles released during radioactive decay that can cause harm if ingested.
  7. A form of radiation with low penetration power but can be dangerous if internalized.
  8. A type of radiation consisting of helium nuclei, which poses health risks when ingested.
  9. A form of ionizing radiation that consists of alpha particles, emitted during the decay of certain heavy elements.
  10. A type of radiation that consists of helium nuclei and is hazardous when introduced into biological systems.

1:Alpha Radiation

用法:

這是指由α粒子所組成的輻射,通常來自放射性衰變的過程。α輻射是一種低穿透力的輻射,對外部環境的影響有限,但對內部器官卻可能造成嚴重傷害。由於其較大的質量和電荷,α粒子在物質中能夠造成較大的損傷。

例句及翻譯:

例句 1:

α輻射在醫療應用中有時用於治療某些癌症。

Alpha radiation is sometimes used in medical applications to treat certain cancers.

例句 2:

這種放射性物質會釋放α輻射,對環境造成影響。

This radioactive material emits alpha radiation, affecting the environment.

例句 3:

α輻射的危害主要來自於其進入人體後的影響。

The danger of alpha radiation primarily comes from its effects once it enters the human body.

2:Alpha Particles

用法:

α粒子是由兩個質子和兩個中子組成的粒子,這些粒子在某些重元素的衰變過程中釋放出來。α粒子的質量較大,帶有正電,這使得它們在與物質相互作用時能夠造成較大的損傷。

Alpha particles are the heaviest particles released during radioactive decay.

3:Alpha Emission

用法:

這是指某些不穩定原子核在衰變過程中釋放出α粒子的過程。α輻射是這種衰變的一種形式,通常伴隨著其他形式的輻射。這種過程對於核能的應用和放射性廢物的處理具有重要意義。
