Radiation Concerns Community after Idaho Wildfire Burns Mining Sites
According to the Huffington Post, a wildfire in east-central Idaho has burned three former mining sites that contain traces of radioactive thorium and uranium. The conflagration is now approaching a fourth mining site, although officials have reported that the risk to human health is low. The radiation in the mines compounds an already difficult situation: the blaze has ignited 333,000 acres of ...

ASTM F1190 - 11 standard guide for neutron irradiation of unbiased electronic components
Semiconductor devices can be permanently damaged by reactor spectrum neutrons (1, 2) . The effect of such damage on the performance of an electronic component can be determined by measuring the component’s electrical characteristics before and after exposure to fast neutrons in the neutron fluence range of interest. The resulting data can be ...

ASTM D4691 - 11 standard practice for measuring elements in water by flame atomic absorption spectrophotometry
Elemental constituents in water and wastewater need to be identified to support effective water quality monitoring and control programs. Currently, one of the most widely used and practical means for measuring concentrations of elements is by atomic absorption spectrophotometry. The major advantage of atomic absorption over atomic emission is the almost total lack of spectral interferences. In ...

Overflowing Tank Cause of New Leak at Fukushima
Another day, another radioactive-water spill. The operator of the crippled Fukushima Dai-ichi nuclear plant says at least 430 liters (110 gallons) spilled when workers overfilled a storage tank without a gauge that could have warned them of the danger. The amount is tiny compared to the untold thousands of tons of radioactive water that have leaked, much of it into the Pacific Ocean, since a ...
