For half a century, our view of the world has been based on the standard model of particle physics. However, this view has been challenged by theories 1 that can overcome some of the limitations of ...

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 ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...

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 ...

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 ...

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 ...

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 ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...
