Geiger’s law can be expressed in the form
A
R = bE3/2
B
R = bE4/2
C
R = bE5/2
D
R = bE6/2
Explanation: 

Detailed explanation-1: -radioactive decay analysis …and proposed a remarkably successful equation for the decay constant, log = a + b log r, in which r is the range in air, b is a constant, and a is given different values for the different radioactive series.

Detailed explanation-2: -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.

Detailed explanation-3: -The Geiger–Nuttall (GN) law relates the partial -decay half-life with the energy of the escaping particle and contains for every isotopic chain two experimentally determined coefficients. The expression is supported by several phenomenological approaches, however its coefficients lack a fully microscopic basis.

Detailed explanation-4: -Gamow’s theory of alpha decay derivation explains the phenomenon of alpha decay. Gamow made the following assumptions: An alpha particle may exist as an alpha particle heavy nucleus. An alpha particle is in constant motion and is held in the nucleus by a potential barrier.
