Isotopes and their Uses
Research
-
-
CARBON DATING determines how old fossils and certain artifacts are. Living organisms absorb C-14 and after their death it starts to decay at a known rate (half life), scientists can measure how much is left and determine how old it is.
-
Fossils ~ 50,000 years old
Medicine
-
-
Thyroid scans and cancer treatment. Thyroid glands absorb iodine including iodine 131, Beta rays kill overactive cancerous thyroid cells and gamma rays can be tracked by a scanner to pinpoint threats due to low half life
