In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

Add Yahoo as a preferred source to see more of our stories on Google. The findings of a new study suggest radioactive decay rates — long considered physical constants — are more variable than ...

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

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 ...

Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through a stunning three-proton emission sequence, shedding light on nuclear ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

OAK RIDGE, Tenn., March 11, 2019--An international collaboration including scientists at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) solved a 50-year-old puzzle that ...
