Question

What is Geiger nuttall law

Answer 1

Answer:

In nuclear physics, the Geiger–Nuttall law or Geiger–Nuttall rule relates the decay constant of a radioactive isotope with the energy of the alpha particles emitted. Roughly speaking, it states that short-lived isotopes emit more energetic alpha particles than long-lived ones.

The relationship also shows that half-lives are exponentially dependent on decay energy, so that very large changes in half-life make comparatively small differences in decay energy, and thus alpha particle energy. In practice, this means that alpha particles from all alpha-emitting isotopes across many orders of magnitude of difference in half-life, all nevertheless have about the same decay energy.

Formulated in 1911 by Hans Geiger and John Mitchell Nuttall as a relation between the decay constant and the range of alpha particles in air, in its modern form[citation needed] the

Geiger–Nuttall law is

Geiger–Nuttall law is

{\displaystyle \log _{10}\lambda =-a_{1}{\frac {Z}{\sqrt {E}}}+a_{2}}{\displaystyle \log _{10}\lambda =-a_{1}{\frac {Z}{\sqrt {E}}}+a_{2}}
