Rate radiometric dating
If Earth was experiencing a rapid expansion of space during an accelerated decay event it would remove the excess heat quite effectively.A local rapid expansion could result from time dilation.(Talk Origins quotes in blue) The fact that there is some supporting evidence for an assumption only increases the reasonableness of the assumption, but in this case it is still an assumption .
All processes in nature vary according to different factors, and we should not expect radioactivity to be different. Scientific Creationism, Green Forest, AR: Master Books, p. Creation Wiki response: The first thing that needs to be noted is that the wording of this claim is not found in Morris' book.
This is Talk Origins' interpretation of his actual comments.
This article (Radiometric dating falsely assumes rates are constant (Talk.
Origins)) is a response to a rebuttal of a creationist claim published by Talk.
The report containing the charts called Radiometric dates from Alaska - a 1975 compilation  is simply a chart of data with no interpretation beyond the date calculations.
Now 62% of the locations had only one date and so there was nothing to compare the dates to.
Assuming that it is necessary that all decay methods change to the same extent, both proposed periods of accelerated decay are thought to have occurred during Creation and the Flood, and as such they were acts of God—literally.

So the likelihood of it occurring naturally is irrelevant. Furthermore a study of a survey of radiometric dates from Alaska showed no statistical tendency towards agreement.
Reference: Helium Diffusion Rates Support Accelerated Nuclear Decay Reference: Radioisotopes and the Age of the Earth First of all, this only shows that decay rates are not varying right now. In the case of Beta decay the factor is a billion fold.
