The explosion and nine-day fire sent radioactive isotopes in many directions, and ended up causing incalculable amounts of biological damage and death. It's still highly radioactive today.) So now that we understand how it works, the evolutionist theory for C14 dating states that if you test an object for C14, and it only has about half the amount of C14 known to be in the atmosphere (i.e.
0.00003825%), then that object has been dead for about 5700 years.
The authors relied on the particularities of 14C concentration in the atmosphere, which are well-known for the period ranging from the mid-1950s to the present.
Choosing the right physical technique to analyse paintings can make all the difference when it comes to ascertaining their authenticity.
Now, a painting initially attributed as belonging to a series called 'Contraste de formes' by French Cubist painter Fernand Léger has definitely been identified as a forgery.
They are: (1) the C14 concentration in a specimen at its time of death; (2) the decay rate of C14; (3) the current C14 concentration in the specimen being “dated”; and (4) if anything else has affected the specimen’s C14 content. The curved line represents the declining amount of C14 atoms over time due to radioactive decay.
Note: only the third of those four necessary facts can be measured, the other three must be estimated, assumed, or extrapolated. During each half-life (~5,730 years), about half of the remaining C14 atoms in a specimen are expected to decay.

Though they demonstrated that the fibres in the canvases differed and that different pigments were used in the two paintings, they did not arrive at conclusive evidence.
