The rate at which nuclear day takes place is measured by the isotopes half-life. The half-life is the time taken for 50% fo the nuclei to decay. Gold-200 has a half-life of 48 minutes. Cobalt-60 has a half lif of 5.3 years. Uranium-238 has a half life of 4.5 million years. Order these from the longest to the shortest in terms of half-life.
uranium-238
cobalt-60
Gold-200

alpha
+2
beta
-1
gamma
0
