My point any way was that the earth would be irradiated extremely.
This is an utterly useless statement unless you do the math and demonstrate what the actual
quantitative values would be. It is also a kind of speculation that isn't really worth voicing unless you are open to learning about the subject and from that learning reconsidering your views.
Very few here that make such speculations (which are basically clutching at straws attempting to support an unsupportable position) are willing to modify their views based on learning anything new.
Additionally, do you actually think that, in several decades, if the numbers were that radioactivity would have been "extremely" higher in the distant past that someone in the geologic or geophysics community would not have thought of actually doing the calculations? I'm actually very interested in your answer to this question as it indicates your degree of understanding of the kind of thinking that has been done.
