the large amount of water causes rapid decay of dead organisms
This describes the theory of punctuated equilibriumdeveloped by Stephen Jay Gould and Niles Eldridge.
Punctuated equilibrium See link below.
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
alpha decay, beta decay, and gamma radiation
The rapid decay theory explains the decrease in the strength of the earth's magnetic field better then the dynamo theory. Although the dynamo theory explains the explains the reversals where the field pointed in the opposite directions better. The rapid decay theory allows for it, but only if there is an event of cataclysmic volcanic and geological activity. The rapid decay theory also explains the magnetic fields on the other planets correctly.

Look for the answer in your book. Its there.
If you're talking about what I think you're talking about, the fact that it is not "scientifically valid" might have a lot to do with it.
If the rapid-decay theory is true, it posits that radioactive decay rates were once much higher, leading to a faster rate of radioactive decay in the past. However, this theory does not necessarily require a catastrophic event like a worldwide flood in Noah's time. The flood story is not directly related to the rapid-decay theory and is not considered an essential part of earth's history from a scientific perspective.
The theory of puctuated equilibrium.
The theory of rapid evolution rather than over a very long time.
The Big Bang Theory - 2007 The Loobenfeld Decay 1-10 is rated/received certificates of: Argentina:13 Netherlands:AL
Acceptance of the germ theory provided the rapid development of hygienic practices, advancements in medicine, and understanding of the causes of infectious diseases.
