A team of scientists from Purdue and Stanford universities has found that the decay of radioactive isotopes fluctuates in synch with the rotation of the sun's core.

The fluctuations appear to be very small but could lead to predictive tools for solar flares and may have an impact on medical radiation treatments.

In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.

To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age.

"One of our next steps is to look into the isotopes used medically to see if there are any variations that would lead to overdosing or underdosing in radiation treatments, but there is no cause for alarm at this point.

Are the fluctuations large enough to call into question currently accepted geological dates? From this article, "By 2050, fresh organic material could have the same $^$C/C ratio as samples from 1050, and thus be indistinguishable by radiocarbon dating.Click on it and you'll get a new page that lists the articles that cited the article in question.
