Thread: Strange problem seems to indicate sterial earth

    Question Strange problem seems to indicate sterial earth

    Radium radioactive alpha beta and gamma rays 1 part per trillionth in earths crust now
    Halflife approx 1600 years.
    .that comes out to septillion times more radium 128 thousand years ago
    therefor the earth was like a reactor core a million years ago.
    Unless halflife is incorrent (unlikely)
    The amount of radium would have doubles thousands of times long before neandrothol existed

    You are assuming a constant half-life over a VERY LARGE period of time. Are you SURE about this assumption?
