This story is inaccurate. C14 naturally occurs and every living thing has C14 in it. When the animal dies, the C14 is not replaced and decays. That is the basis of Carbon dating.

Carbon dating shows humans make new heart cells - The cold war helps settle a hot debate about how hearts grow.

(Unlike in archaeology studies, the half-life of 14C, about 5,700 years, does not affect these results.)

IMHO, the study took advantage of the increase of carbon 14 during that period of atmospheric bomb testing compared to the normal amount of carbon 14 in nature.

Exactly. The C14 levels around after the tests would have zoomed compared to normal background levels.
