Radioactive contamination - Wikipedia Radioactive contamination, also called radiological contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency - IAEA - definition).. Such contamination presents a hazard because of the radioactive decay of the.

Nuclear Chemistry: Half-Lives and Radioactive Dating Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay. A useful application of half-lives is radioactive dating. This has to do with figuring out the age of ancient things. If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able […]

Carbon 14 Dating: How is Carbon-14 produced? How is Carbon 14 produced? A lot of interesting things happen in the upper atmosphere of our world. Much of the high energy photons of the electromagnetic spectrum is filtered out by the time light gets to the surface of the earth: However, in the extreme upper atmosphere there are photons striking the atmosphere of such high energy that they initiate reactions of molecules or even change the.

Carbon-14, Radiometric Dating - CSI Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

6. How long is material radioactive? carbon-14. The older a sample of a radioactive material, the less radioactive it is. The decrease in radioactivity follows a characteristic pattern shown in the graph or decay curve.. The y axis can represent the % radioisotope left OR the measured radioactivity.

Radioactive Dating Game - Radiometric Dating | Carbon. Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
