什麼是中子流???

From direct translation, you may know that Neutron flux merely refers to a current of a large number of neutrons.

It can be created by atomic experiments or natural process.

A strong neutron flux can destroy tissues of living organisms severely because the neutrons is absorbed by the water inside tissues.
However it does do much harm on buildings since neutrons are uncharged, so it will almost pass through the walls completely.


wiki:
Neutron flux is the term applied to the measurement of neutrons passing though a given region of space.
Both within natural processes and in the experimental laboratory, neutron flux may be applied to atomic nuclei, in which nuclei are bombarded with neutrons at a steady rate. This can be used to produce different isotopes, including unstable, radioactive ones, of a given chemical element.

中子是不帶電荷, 原子質量為1的粒子
中子流是大量中子流過, 是一種粒子波
就好像水一樣, 只要把水分子換成中子就可以得出中子流的模型

中子流可由核試驗和某些大自然反應產生

中子流的特性是它會穿過障礙物, 因為中子不帶電荷, 不會被質子或電子吸引
有小量的中子會撞到質子或電子而使前進路線改變, 但這機會很微
中子流會筆直前進, 直至被中子吸收物(neutron absorber)吸收為止

常用的中子吸收物為水, 水也是生物體內的主要成份
所以中子流會對生物造成極大傷害而不毀壞建築物
