A New Angle on the Earth’s Radiation Belts
A new empirical model of energetic electrons from Van Allen Probes data includes pitch angle analysis, revealing insights about radiation belt energization and loss processes.
Radiocarbon in the Oceans
Offsets in radiocarbon concentration within the ocean or between the ocean and the atmosphere are particularly useful proxies for a variety of studies.
IAEA Affirms Japan’s Fukushima-Related Radioactivity Monitoring
Laboratories outside Japan have validated the results. Marine radioactivity levels from the nuclear disaster have fallen, but questions remain years after the meltdown.
