Novel method for low level Sr-90 activity detection in seawater by combining oxalate precipitation and chelating resin extraction
strontium-90 nuclear power plant seawater monitoring preconcentration oxalate precipitation
2017/4/10
Sr released into seawater from nuclear bomb testing and nuclear facility accident sites requires long-term monitoring.
However, measuring 90Sr in seawater is still difficult and time-consuming. This ...
A simple model for the earthquake cycle combining self-organized complexity with critical point behavior
earthquake cycle self-organized complexity critical point behavior
2009/11/12
We have studied a hybrid model combining the forest-fire model with the site-percolation model in order to better understand the earthquake cycle. We consider a square array of sites. At each time ste...
Combining [3He] cosmogenic dating with U–Th/He eruption ages using olivine in basalt
U–Th/He cosmogenic helium Snake River Basalts Idaho olivine
2014/4/8
This paper presents new U–Th/He crystallization and 3He exposure ages on olivine for a suite of basalt samples from the Snake River Plain, Idaho. The results provide the first demonstration that U–Th/...
