  1. We can talk about the half - life of a radioactive isotope, and indeed we can measure and state very very precisely what that half - life is

    我們可以談論放射性同位素的半衰期,我們確實可以非常準確地測量和描述半衰期是什麼。
  2. A radioactive, inert, gaseous isotope of radon, with a half - life of3. 92 seconds

    錒射氣氡的一種放射性的,惰性的和氣態的同位素,其半衰期為3 。 92秒
  3. We have interpreted in the same way the production of radioactive elements in boron and magnesium in the first an unstable nitrogen with a half life of 11 minutes is produced, and in the second, unstable isotopes of silicon and aluminum

    我們還用同樣的方式解釋了在硼和鎂中製造放射性元素的過程:首先製造一種半排出期為11分鐘的不穩定的氮,然後製造不穩定的硅和鋁同位素。
  4. Although almost all this material, which has a 24, 000 - year half - life, has since disappeared ( primarily through natural radioactive decay ), some of the plutonium itself underwent fission, as attested by the presence of its characteristic fission products

    這些物質半衰期為2萬4000年,幾乎已經全部消失(主要是經由自然的放射衰變過程) ,而且部份的鈽本身又經過核分裂,這可由其核分裂產物為證。
  5. After one half - life, the level of radioactivity of a radioactive material is halved, after two half - lives, it is reduced to one quarter and so on

    1 , 260 , 000 , 000年每經過一個半衰期,放射性物質的放射性便會剩下一半,經過二個半衰期,放射性便會剩下原先的四分之一,餘此類推。
