When we used to talk about radiation, we always liked to say that the closest source of nuclear radiation to you was yourself.C14The reason why it can become an archaeological tool is that the body of any carbon-based organism on the earth naturally containsC14Every cell in our body is a source of nuclear radiation. So science says, "Everything above absolute zero is radioactive"

Carbon14It is an isotope that exists in a human body and the natural environment. It releases beta rays, which are short-wave rays. The amount of radiation is very low, and a piece of paper can block it. Take C14 capsules to do breath test, in fact, only in the body to add some extraCarbon 14The amount. The radiation dose of urea carbon 14 is very small (about 1microCi). For example, the amount of radiation from a carbon 14 breath test is almost the same as that of an hour's air travel, so there is really no need to worry too much about radiation.
