Estimating uranium and thorium abundance with geoneutrinos

A planet's interior heat comes from two principal sources: leftover energy amassed from collisions between planetesimals during the accretion of the planet and the subsequent decay of radioactive elements embedded within ...

Moon's largest crater holds clues about early lunar mantle

Despite our long history with Earth's closest celestial neighbor, much remains unknown about the moon, including about asymmetries between its near side and far side, for example, in crustal thickness and evidence of volcanic ...

New approach yields high-purity radium for medical applications

Producing radium isotopes to treat cancer could get easier. Researchers developed a method to recover medical radium isotopes. The process begins with the dissolved proton-irradiated thorium target solution. The process then ...
