English term or phrase: fallout
Definition from European Nuclear Society:
Radioactive material which falls back to the earth after the release into the atmosphere (e.g. by nuclear weapon tests, accidents). The fallout occurs in two forms: the close fallout consists of heavy particles which fall to the ground within some days near the place of release and in an area which, depending on the weather conditions, may reach up to several hundred kilometres in the wind direction. The world-wide fallout consists of lighter particles reaching higher atmospheric layers and distributed over a wide part of the earth because of atmospheric currents.

Example sentence(s):
  • Fallout creates large areas of contamination and the ionizing radiation coming off the fallout, which can damage tissues and penetrate through thin walls and glass US Department of Health & Human Services
  • The chemical properties of the different elements in the fallout will control the rate at which they are deposited on the ground. The less volatile elements will deposit first. Wikipedia
  • Weather conditions can affect fallout immensely. Particularly rainfall can "rain out" fallout to create very intense localized concentrations. University of Michigan

  • 原子或熱核子爆炸時,散播於大氣中並漸次降落至地面之放射性物質。 落塵通常分為三類:(a) 本地或近距落塵(Local or Close-in fallout), 在爆炸地點之鄰近 (多在下風處) 發生於數小時之內。其所含主要質點直徑大於25微米,大多數地面物質因附著而沾染放射性。本地落塵所含分裂物約佔總量百分之二十至八十 (視爆炸之位置及類型而異) 。(b) 中距或對流層落塵(Intermediate or Tropospheric fallout), 在大氣中停留數週至數月之久,主要隨降水降落,亦有受重力作用下降者,對植物構成侵害。此種落塵在全部分裂物中所佔百分數甚低。(c) 延遲性或平流層落塵(Delayed or Stratosphericfallout) , 由高空爆炸將原子雲沖入平流層所致。其在高空停留之時間自不足一年乃至十年之久,視爆炸之緯度與高度而異。其質點直徑均遠在一微米之下。 - 氣象科技研究
