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 ...

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 ...

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 ...

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 ...

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 ...

Although metal alloys is not among the most exciting topics for most people, the moment you add the word ‘radioactive’, it ...

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

Analysis of meteorite Erg Chech 002 shows that the radioactive isotope aluminum-26 was unevenly distributed in the early Solar System, overturning previous theories. (Yuri Amelin) A little over four ...
