Supernovae showered Earth with radioactive debris

An international team of scientists has found evidence of a series of massive supernova explosions near our solar system, which showered the Earth with radioactive debris.

Tracing deep ocean currents

Radioactive isotopes typically take four years to reach the Norwegian coast from Sellafield on the north-eastern coast of England. Researchers like Yongqi Gao follow the radioactive waste to understand how ocean currents ...

A versatile optical sensor for the characterization of fluids

Laser self-mixing is a technique usually used for the measurement of low velocities and vibrations. In a paper that has just been published in the journal Nuclear Instruments and Methods A, researchers from the Cockcroft ...

Scientists help avert a nuclear medicine meltdown

University of British Columbia scientists have shown that small cyclotrons – particle accelerators the size of an SUV – can replace hulking nuclear power plants as the country's main source of medical isotopes, the radioactive ...

No Fukushima radiation found in coastal areas

It was raining when Eric Norman, Berkeley Lab physicist and University of California (UC) Berkeley professor of Nuclear Engineering, heard about the nuclear-reactor meltdown in Fukushima, Japan. "I immediately thought of ...
