Unlike archaeological radiocarbon dating based on the fixed rate of decay of the carbon-14 isotope, there is simply no fixed rate of decay of basic vocabulary, which would allow us to date ancestral proto-languages.

Whereas if we were really close to expiration, there is a greater chance of all of the premium being lost on the option that is opposite of the stock price movement as the rate of time decay will increase exponentially.

On checking equipment in his laboratory, he was surprised to discover that the rate of radioactive decay changed before the solar flare.

Checking data collected at Brookhaven National Laboratory on Long Island and the Federal Physical and Technical Institute in Germany, they came across something even more surprising: long-term observation of the decay rate of silicon-32 and radium-226 seemed to show a small seasonal variation.

The GAO found that one in three children had untreated tooth decay twice the rate of those covered by private insurance and one in nine had untreated decay in three or more teeth.

These negotiations will determine the rate of integer-value decay and will revalue numbers accordingly.

Physicists have long held the view that the rate of breakdown - or decay - for any given radioactive substance is constant.

The team of physicists was investigating the possibility of using radioactive decay rates to generate random numbers, since the rate is constant but the emission of individual atoms is unpredictable, it seemed like a perfect fit.
FORBES: Radioactive Decay Rates May Not Be Constant After All

According to Mr Bryan, who runs the college's architectural stone conservation course, the structure is sound but work is needed to slow its rate of decay.

It is unclear how solar particles affect rates of radioactive decay, but Prof Jenkins asserts that "either neutrinos are affecting the decay rate or perhaps an unknown particle is".
