How to solve radioactive dating problems
It is through this mechanism that the radiometric age of the universe is usually calculated as being on the order of ten billion years.
Professor Fowler did exactly this and has maintained his calculated radiometric age for the universe at about 10 billion years, with which I am basically in agreement.
I emailed you about this topic a year or two ago, and I've since taken a class in radioisotope chemistry at UCI.
As a result I was using some of my texts to examine the decay of Americium 241 and noted the naturally occurring decay chains for U235, U238 and Th232, as well as the fully decayed chain for Pu241.
The conclusion is that neutron induced reactions in ores, though minimal now, would have been even more minimal with higher light speed, so no chain reaction would occur.
