Circulating radioactivity

WebJul 20, 2024 · Radiocarbon dating is the process of determining the age of a sample by examining the amount of 14 C remaining against its known half-life, 5,730 years. The reason this process works is because when organisms are alive, they are constantly replenishing their 14 C supply through respiration, providing them with a constant amount of the isotope. WebRadionuclides can enter the body by ingestion, inhalation, or injection. Once taken into the body, their radiation effects depend on their anatomic distribution, duration of retention in the body, and rate of radioactive decay, as well …
