Web19 Apr 2013 · The half-life of radium-226 is about 1602 years, so the question, which asks after the change in 800 years actually asks about "half a half-life" of a 2.5 gram sample. We don't need a calculator ... Web6 Jul 2024 · The rate of radioactive decay is expressed by the relationship: k = 0.693/t 1/2. where k is the rate and t 1/2 is the half-life. Plugging in the half-life given in the problem: k = 0.693/1620 years = 4.28 x 10-4/year. Radioactive decay is a first order rate reaction, so the expression for the rate is: log 10 X 0 /X = kt/2.30.
WebFor example, radium-226 has a half-life of 1,602 years, an mean lifetime of (1,602)/ ln 2 = 2,311 years, and a decay rate of 1/ (2,311) = 0.000433 per year. In other words, 0.0433 percent of the radium decays away each year, or 433 parts per million per year.
