Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

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.

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 ...

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 ...

Nearly 15 years after the Fukushima nuclear disaster, air radiation doses have dropped significantly in Fukushima Prefecture, ...

Alpha recoil: Conceptual drawing of the experiment, which detects the nuclear decay of individual helium nuclei by embedding radioactive atoms in a micron-sized object and measuring the object’s ...

The analysis concluded that the decay heat from these radioactive elements could support the life activities of more than ...

Scientists poke and prod at the fringes of habitability in pursuit of life’s limits. To that end, they have tunneled kilometers below Earth’s surface, drilling outward from the bottom of mine shafts ...
