Krypton used to accurately date ancient Antarctic ice

A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating – a new technique that may allow them to locate and date ice that is more than a million years ...

Officials: No health risks for US nuke workers

(AP)—Thirteen employees who were exposed to radiation during a leak at the nation's only underground nuclear waste dump aren't likely to experience any health effects, federal officials said Wednesday.

Study could help improve nuclear waste repositories

(Phys.org) —Here's the question faced by a team of Sandia National Laboratories researchers: How fast will iodine-129 released from spent nuclear fuel move through a deep, clay-based geological repository?

Gold used to test reactor beam quality, intensity after upgrade

(Phys.org) —A little engine work is a nice excuse to take a roadster for a spin and see how it performs. Similarly, a recent upgrade to a nuclear research workhorse at Idaho National Laboratory is driving verification of ...

Exotic isotopes step on the scale

Elements heavier than iron are believed to have formed in supernovae or merging neutron stars through a series of complex nuclear reactions. Nuclear physicists are working to recreate these reactions by performing simulations, ...

Toxic radiation 'in groundwater' at Fukushima

Toxic radioactive substances have once again been detected in groundwater at the crippled Fukushima nuclear plant, its Japanese operator said on Sunday, the latest in a series of incidents at the tsunami-battered complex.

Sulphur from yeast helps to track animal protein pathways

Researchers from the University of Oviedo (Spain) have labelled sulphur in brewer's yeast with a non-radioactive method so that when feeding it to laboratory rats the course taken by the element can be tracked and the amino ...
