Radiochemical dating and radioactive isotopes
In particular the use of natural and anthropogenic radionuclides as tracers of natural processes, such as rates of sediment mixing, transport and accumulation.• The dating of recent sediments – particularly using 137Cs and 210Pb.To do this it has to undergo irradiation which commonly uses radioactive isotopes of cobalt-60.Besides preventing illness, irradiating food can help it stay fresher longer because it gets rid of microorganisms and bacteria that cause early spoilage.The good news is the irradiated food doesn't come into direct contact with the radioactive isotope, so the food won't be radioactive.Do you ever notice when you buy paper that the thickness is uniform?Radioactive isotopes have an unstable nucleus that decays or emits excess energy or radiation until the nucleus becomes stable.They can be naturally occurring or artificial isotopes of an element.
If an isotope has an unstable nucleus that breaks down to emit radiation, then these are what we call radioactive isotopes, also known as radioisotopes.
Here are some radioactive isotopes and the roles they play in research.
Radioactive isotopes, also known as radioisotopes, have unstable nuclei that emit energy in the form of radiation until their nuclei becomes stable.
This is very important in determining when the organism died, so it is very valuable in determining ages of fossils and organisms that are thousands of years old.
Radioactive isotopes are also important in other aspects of research like the complex chemical processes of photosynthesis.
In this lesson, we will learn all about radioactive isotopes and their uses.
