Carbon dating atom bomb

When these fossils exist, they can be used to determine the age of the strata, because the fossils show that the strata correspond to strata that have already been dated by other means.For more information on radiometric dating, read Radiometric Dating and the Geological Time Scale, Circular Reasoning or Reliable Tools? Given that the half-life of carbon-14 is 5730 years, one can calculate that 4 billion C-14 atoms will produce 1 decay per minute on the average.

I searched and couldn't find any information about this, can you guys help me?

There many other dating methods that are used to date things; one of witch is chemical properties of igneous rock formations. To answer your question, nuclear weapons testing brought about a reaction that simulated atmospheric production of carbon 14 in unnatural quantities.

The huge thermal neutron flux produced by nuclear bombs reacted with nitrogen atoms present in the atmosphere to form carbon 14.

When an organism dies, it ceases to take in new carbon-14, and the existing isotope decays with a characteristic half-life (5730 years).

The proportion of carbon-14 left when the remains of the organism are examined provides an indication of the time elapsed since its death.
