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 ...

Interatomic Coulombic Decay (ICD) is a non-local electronic relaxation process that occurs in weakly bound systems, in which an electronically excited atom or molecule transfers its excess energy to a ...

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.

For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...

Nuclear decay and fusion dynamics constitute central pillars in modern nuclear physics, with implications ranging from energy production and astrophysical phenomena to the synthesis of novel elements.

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 ...

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 ...

Scientists have discovered a new type of uranium that is the lightest ever known. The discovery could reveal more about a weird alpha particle that gets ejected from certain radioactive elements as ...

Researchers investigated the long-term contamination of Lake Onuma in Japan resulting from the 2011 Fukushima Daiichi nuclear disaster. They devised a formula based on a framework known as the ...

A new study by Dutch scientists has dramatically shortened the predicted lifespan of the universe, showing that it will decay much faster than previously thought. The groundbreaking calculations, ...
