In this method, the sample is in liquid form and a scintillator is added.

This scintillator produces a flash of light when it interacts with a beta particle.What methods do they use and how do these methods work?In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.­ ­You probably have seen or read news stories about fascinating ancient artifacts.At an ar­chaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.
