If the half life of a radioactive substance is 4 days. Calculate the time required to decrease the concentration of 1/8th of original??
Half life of a radioactive substance is defined as the time taken for it to degrade to 1/2 of its original quantity.
I like looking at the problem this way
So it reaches
The time required, therefore, to decrease the concentration of 1/8th of original would be
Now, this is the formula approach.
