Explain how radioactive and radiometric dating are related

Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Many rocks and organisms contain radioactive isotopes, such as U-235 and C-14.

Learn about different types of radiometric dating, such as carbon dating.

Understand how decay and half life work to enable radiometric dating.

As long as an organism is alive, the amount of C-14 in its cellular structure remains constant.

If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able to predict when that particular atom might decay.

The rule is that a sample is safe when its radioactivity has dropped below detection limits. So, if radioactive iodine-131 (which has a half-life of 8 days) is injected into the body to treat thyroid cancer, it’ll be “gone” in 10 half-lives, or 80 days.

This stuff is important to know when using radioactive isotopes as medical tracers, which are taken into the body to allow doctors to trace a pathway or find a blockage, or in cancer treatments.

  1. Male circumcision is rare in Denmark, rare enough that circumcised males are epidemiologic outliers, which may lead some of them to feel “different,” leading to anxiety about sexual experiences with women who perceive a circumcised penis as abnormal.
