Web(April 2011) This is a list of radioactive nuclides (sometimes also called isotopes ), ordered by half-life from shortest to longest, in seconds, minutes, hours, days, and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

It's passed 6 hours since the original administration of the drug. This is how you calculate its current level: Divide the time that's passed by the drug's half-life (6 / 12 = 0.5).; Raise a half to the power of the result from step 1 (0.5 0.5 = 0.707). highest rated 46 inch tv
