Solution - Calculate Its Half Life Period. - HSC Science (Electronics) 12th Board Exam - Physics

Question

The decay constant of radioactive substance is 4.33 x 10-4 per year. Calculate its half life period.

 

Solution

Here, λ= 4.33 * 10−4 per year

t1/2 = `0.6931/lambda`

∴ t1/2 = `0.6931/lambda =0.6931/(4.33*10^-4)`

 ∴t1/2 = 1600.69 years or

 t1/2 =0.16*104*365 days

∴t1/2 = 584000days
