Decay rate anomalies
« on: November 26, 2008, 03:06:42 AM »
The current issue of Science News (Nov. 22) has a very interesting article about an apparent seasonal variation in radioactive decay rates seen in several experiments. This is probably some sort of artifact but you never know...

Certainly not something to be dismissed out of hand. Decay rates of a few nuclides have been known to vary for other reasons. 7Be is a fairly well known example. The 0.0765 keV IT decaying isomer in 235U is another. Anything that decays by EC is obviously igoing to see decay rate changes if the atom is completely ionized.

This study is interesting because it deals with alpha and beta decay which occur entirely within the nucleus.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
