[split] Radiometric Dating

[Creatard]

Holy necropost.

These "problems" are very overblown and inaccurately characterized by creationists.

Can't say I'm surprised you used that site. It deals with problems 2 and 3, but you still need to answer for one.
It does not address the effects of earth's magnetic field, only pressure and temperature.
Its contention with constant decay rates was met with isochrones, which assumes a known amount of sister isotopes. Isochrones were applied to the K-Ar dating during the tests for lava flows at Mt. Ngauruhoe, an initial failure because flows known to be 50 years old were given ages over 270,000 years old. When isochrones were applied, the difference was made even worse(Pb-Pb, also tested on site with isochrones, gave an estimate that multiplied the real age by a factor of 70,000,000.) From observable instances, not the computer generated ones, isochrones have not shown to increase reliability. For more see http://www.trueorigin.org/dating.asp#Possible changes in the decay rate
