Here’s a hypothesis for you: radioactive decay varies over time, possibly with a yearly cycle. [Panteltje] decided to test this hypothesis, and so far has two year’s worth of data to comb over.

Planning and Carrying Out Investigations: Designing experiments to measure radioactive decay and the effects of radiation. (Example: Conducting experiments to observe how distance and shielding ...

Two decades in the making, a new flagship facility for nuclear physics opened on May 2, and scientists from the Department of Energy's Oak Ridge National Laboratory have a hand in 10 of its first 34 ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

Two independent teams of nuclear physicists have found evidence for a new form of radioactivity involving the simultaneous emission of two protons. Researchers at the GANIL laboratory in France and ...
