Nuclear weapons tests are among the most violent events humans can trigger, and that violence leaves fingerprints in the ...

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.

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 ...

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.

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 ...

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 ...

Cause and Effect: Understanding the causes of radioactive decay and its effects on materials and organisms. (Example: Exploring how distance and shielding materials affect exposure to radiation.) ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...

Radiometric dating, utilizing the predictable decay rates of radioactive isotopes within rocks and other materials, is the primary method for determining the age of geological samples. Multiple ...

Isotek Systems, in partnership with TerraPower Isotopes, co-created by Bill Gates, are “producing cancer treatment material ...
