1 Bq = 2.7 x 10 -11 Ci
1mCi = 1 x 10-3 Ci, thus, 1 x 10 4 mCi = (1 x 10 4) 1 x 10-3 Ci = 10 Ci
1
Ci = 1 x 10 -6 Ci . thus, 10
Ci = 10 x 1 x 10 -6 Ci = 1 x 10
-5 Ci
Thus, the smallest amount of radioactivity is represented by 1 Bq (= 2.7 x 10 -11 Ci )

220AL-E1 he uncertainty in an experimental quantity must be reported. Since there are a number of ways to do this we must state the meaning of the uncertainty. A Estimated uncertaint Sometimes we make several measurements that are identical. Eq 1-2 would yield ơx-0, which could lead to the mistaken impression that the uncertainty is zero when in fact the precision of the instrument is less than the random errors. We must estimate the uncertainty, and,...
