what i want to do in this video is kind of introduce you to the idea of , one , how carbon-14 comes about , and how it gets into all living things . and then either later in this video or in future videos we 'll talk about how it 's actually used to date things , how we use it actually figure out that that bone is 12,0... | so carbon-12 is the most common . so most of the carbon in your body is carbon-12 . but what 's interesting is that a small fraction of carbon-14 forms , and then this carbon-14 can then also combine with oxygen to form carbon dioxide . and then that carbon dioxide gets absorbed into the rest of the atmosphere , into o... | is carbon 14 production pretty uniform throughout time ? |
