- 5List Some RadioisotopesCarbon-14
Cobalt- 60
Iodine - 131 - 6Uses of RadioisotopesCarbon 14 is used for Carbon Dating
Cobalt 60 is used in radiotherapy treatment for cancer
Iodine 131 is used as a medical tracer - 7How is Carbon-14 used in Carbon dating?The relative abundance of carbon-14 in living organisms is constant due to constant replenishment. When organisms die the carbon-14 is no longer replenished then go to the process of nuclear decay and falls according to its half life. This time scale is then used in determining the age of the artifact
