Purdue carbon dating
For example, a team at Purdue University in Indiana was monitoring a lump of manganese-54 in a radiation detector box to measure the isotope’s half-life.At PM on December 12, 2006, the instruments recorded a sudden dip in radioactivity.
“People just sort of forgot about it, I guess,” commented David Alburger, the Brookhaven scientist who had conducted the experiment (Ibid).
Alburger was unaware that, at the exact same time, the German scientists at the PTB had found the same thing, with “yearly oscillations in a decay rate, in a 15-year experiment with radium-226” (Ibid.).
Again, the finding made no splash in the scientific community.

The great scientist Ernest Rutherford was the first to define the concept of “half-life,” that is, the time it takes for one half of the atoms in a given quantity of a radioactive element (such as plutonium) to decay into another element (such as uranium), or for one isotope of an element (such as carbon-14) to decay into another isotope of that same element (such as carbon-12).
