The most radioactive elements found on Earth include Polonium, Radium, and Radon. Learn why elements with short half-lives, ...

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 ...

For obvious reasons, radioactive material is a restricted commodity. Users must go through radiation safety training and the project approval process before they can begin ordering and using ...

What do a capsule in Australia, a cylinder in Thailand and a camera in the US have in common? All three contained radioactive material and went missing over the past three months, in what experts say ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

A new study identifies internal heating from radioactive decay as a critical factor in a planet’s ability to generate a magnetic field and retain an atmosphere. Credit: Illustration by Melissa Weiss ...

An international team of astronomers including Stella Offner of The University of Texas at Austin has proposed a new method for the formation of aluminum-26 in star systems that are forming planets.

Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns. Researchers now show that a 40-year-old mathematical discovery can be ...

ST. PAUL, Minn. – Xcel Energy says it has fixed the pipe leak at its nuclear power plant in Monticello and will reopen it soon. Last fall, at least 400,000 gallons of water containing radioactive ...

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 ...
