If 30% of a sample of radioactive isotope decays in 24 hours, what is the half-life?What is a half-life, and why do we care about the half-lives of commonly used radioactive isotopes?1. A sample of a radioactive isotope is found to have lost 79.9% of its original activity a...
DU is less radioactive than natural uranium because it has less U-235 per unit of mass. All traces of decay products have been removed during the chemical purification of uranium prior to enrichment. DU can be disposed of as low-level radioactive waste or used in the fabrication of mixed ...
The isotope 88 224 Ra of radium has a decay constant of 2.62 x 10^-6 per second. What is the half-life (in days) of this isotope? A radioactive nucleus is being produced at a constant rate \alpha per second. Its decay constant is \gamma. If N...
to 1971, predicted in 1970 that, by the year 2000, plutonium “can be expected to be a predominant energy source in our lives.” By contrast, the molten salt reactors were mostly intended as a pathway to use thorium, which was more plentiful than uranium, by converting it into uranium-...
The radioactivity ofradiumthen must be enormous. This substance is the most radioactive natural element, a million times more so than uranium. Why is plutonium so rare? The reason that plutonium (and other transuranic elements) are so rare in nature is thatbeing radioactive, they decay with ...
” In theiranalysis of public water system data collected between 2010 and 2015, EWG focused on six radioactive contaminants, including radium, radon and uranium.They found that California has more residents affected byradiation in their drinking water than anywhere else in the U.S. Yet the ...

Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
The widespread use of fracking in the United States began in 2007 and heralded a boom in energy production in the country. In the decade that followed its natural gas output rose 40 per cent, prices fell by more than two thirds and America went ...
The half life period of radium is 1600 years.In how many years 1 gram of radium lose 1 centigram? A container holds a pure sample of a radioactive substance with a half-life of 2 hours. Which of the following statement are true? Choo...
