Radio dating problems

Ra, a common isotope of radium, has a half-life of 1620 years.
And this big sequence is then used to 'correct' C14 dates. (3.) Even if the rate of decay is constant, without a knowledge of the exact ratio of C12 to C14 in the initial sample, the dating technique is still subject to question.
(4.) Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay.
If something carbon dates at 7,000 years we believe 5,000 is probably closer to reality (just before the flood).
Robert Whitelaw has done a very good job illustrating this theory using about 30,000 dates published in Radio Carbon over the last 40 years.
So when you hear of a date of 30,000 years for a carbon date we believe it to be early after creation and only about 7,000 years old.Despite this she continually uses the c14 dates to create 'absolute' chronologies.She says this is ok so long as you take into account the correction factors from dendrochronology.Knowing this, calculate the first order rate constant for the decay of radium-226 and the fraction of a sample of this isotope remaining after 100 years.Sign up for INFObytes and receive an MP3 (audio presentation) called Genesis, The Gospel and the Creation/Evolution Issue by Dr Emil Silvestru—free for you to download!
