150,000 tons of radioactive waste were dumped in the Atlantic. Decades later, it's visibly oozing.
The second half of the 20th century was something of a golden age for nuclear technology. Following the atomic devastation of WWII, the world found new, more benign uses for radioactive decay. Power ...
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 ...
We think of radioactive material as something buried away in bunkers with bombs, power plants, and maybe some exotic medical equipment. But turns out, there are little bits of radiation in the water, ...
The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the ...
