Answer 2

If R is range of α - particles and I is decay constant then Geiger - Nuttal Law is ..

answer : option (D) logI = a + b logR

solution : A German physicist Johannas Willhelm Geiger together with a British physicist John Mitchell Nuttal observed regularities of rates for even - even nuclei and they proposed Avery important equation equation for decay constant, logI = a + b log R

where R is range in air, I is decay constant , b is constant and a is different values for the different radioactive series.

Therefore correct option is (D) logI = a + b logR
