Question

Half Life 2 What is the approximate half life (s) of the radioactive isotope for which the activity is plotted below? Full scale is t = 800 seconds and N = 10000 counts. (Translation: the horizontal axis displays the t-interval from 0 to 800 s, and the vertical axis displays the N-interval from 0 to 10000. A "count" is the occurrence of a radioactive decay event). N 0 0 t(seconds) Hint: The half life is defined as the time it takes for 1/2 of the original nuclei to decay. Remember: t1/2 = 0.693 ?

Step 1

First, we need to find the initial activity (N0) of the radioactive isotope. Since we don't have the exact plot, let's assume the initial activity is 10000 counts. Show more…

What is the approximate half-life (t) of the radioactive isotope for which the activity is plotted below? The full scale is t = 800 seconds and 10000 counts. (Translation: the horizontal axis displays the t-interval from 0 to 800 and the vertical axis displays the N-interval from 0 to 10000, counting the occurrence of radioactive decay events). Hint: The half-life is defined as the time it takes for 1/2 of the original nuclei to decay. Remember: t/2 = 0.693.
