Jerboasite: Naming French Radioactive Matter in the Sahara Samia Henni On February 13, 1960, the French military detonated the first of seventeen atomic bombs in the Algerian Sahara. The site of the inaugural bomb was Reggane—a district with a town, villages, and an oasis—located in th...
Proponents say these accelerators may bring particle beams to bear on new fields and applications: destroying tumors with pinpoint precision, slashing the half-life of radioactive waste, and teasing out the properties of the most fundamental particles of matter. "FFAGs could revolutionize accelerator...
Half-Life formula You can find the half-life of a radioactive element using the formula: wheret1/2is the half-life of the particle,tis the elapsed time,N0is the quantity in the beginning, andNtis the quantity at timet. This equation is used in the calculator when solving for half-life...
Samuel Arbesman, a mathematician at Harvard, calls this "The Half-life of Facts", the title of his new book. In it he explains that this churn of knowledge is like radioactive decay: you cannot predict which individual fact is going to succumb to it, but you can know how long it take...
Figure 1. Radioactive decay reduces the number of radioactive nuclei over time. In one half-lifet1/2, the number decreases to half of its original value. Half of what remains decay in the next half-life, and half of those in the next, and so on. This is an exponential decay, as ...
