Uranium waste is relatively weak, but it is still radioactive and therefore toxic. That is why scientist always look for ways to neutralize that is clean up the uranium once it combines with water, whether it is from natural ore deposits that leach into groundwater, the spent uranium fuel from nuclear facilities or the remains from uranium mining. The half life of uranium is very long: 4.47 billion years for uranium 238 and 704 million years for uranium 235.

That’s why nuclear waste can be present for a long , long time. Also, it is costly to keep leftover uranium. Unfortunately, uranium a heavy metal that has the highest atomic weight among the naturally occurring elements forms a stable bond with the two oxygen atoms of water. This very strong uranyl ion combination, which dissolves easily in water, makes it very hard to separate uranium from the water.

First there was alcohol breathalyzer. Now there’s a portable drug detector. Instead of laboratory testing that takes a long time to obtain results, a sophisticated device can be used to screen individuals who appear to be under the influence of drugs. The drug detector can measure traces of cocaine, heroin, cannabis, and methamphetamines. It uses a cartridge that has sample gathering saliva, and a measurement chamber that contains magnetic nanoparticles. Using frustrated total internal reflection, the cartridge absorbs the saliva then analyzes it.

The results of the analysis are displayed on an LCD screen with a simple color-coded readout. Look for additional information such as “related links” additional sites,” further reading and the like, it is important that you know where the author got all the information. And even when links are available, it is also important to check that the links work. Although all these may sound too time-consuming, but think evaluating websites as a responsibilities.
