- A certain isotope has a half-life of 9.06 h. What is its decay constant in s-1?866-0 hours. A radioactive sample contains 1.55g of of an isotope with half a life of 3.8 days. How much of the in grams remain after 150 tope 11.4 days?The carbon–14 activity in papyrus growing along the Nile River today is 231 decay events per kilogram of carbon. If a papyrus scroll found in the ruins from ancient Egypt has a carbon–14 activity of 160 decay events per kilogram of carbon, how old is the scroll? (Answer is not 3036)
- Radioactive decay can be described by the following equationln A = ln A0 - ktwhere A0 is the original amount of the substance, A is the amount of the substance remaining after time t, and k is a constant that is characteristic of the substance.For the radioactive isotope strontium-90, k is 2.47 x 10-2 years -1.If the original amount of strontium-90 in a sample is 38.9 mg, how much strontium-90 remains after 28.4 years have passed?_____ mg.What time interval elapses while 51.0% of the radioactivity of a sample of 7233As disappears, as measured by its activity? The half-life of 7233As is 26 h.A radioactive substance decays from 60mg to 12.6mg in 20 years according to the exponential decay model y=ae-bx, where a is the initial amount and y is the amount remaining after x years. a) find the b -value b) Use the exact b-value to write the exponential decay model for this substance with initial amount 60 mg, then use that model to find the half-life.
- The half-life for the decay of carbon-14 is 5.73*10^3 years. Suppose the activity due to the radioactive decay of the carbon-14 in a tiny sample of an artifact made of wood from an archeological dig is measured to be 6.1*10^3 Bq. The activity in a similar-sized sample of fresh wood is measured to be 6.9*10^3 Bq. Calculate the age of the artifact. Round your answer to 2 significant digits.In a piece of rock from the Moon, the 8/Rb content is assayed to be 1.89×1010 atoms per gram of material and the 8/Sr content is found to be 1.08x109 atoms per gram. (The relevant decay is 87Rb → 87Sr + e¯. The half-life of the decay is 4.8 x 10 yr.) 10 (a) Determine the age of the rock. yr (b) Could the material in the rock actually be much older? No, it could not be any older. Yes, it could be much older. (c) What assumption is implicit in using the radioactive-dating method? We assume that none of the 8/Sr nuclei came from the decay of 8/Rb nuclei. We assume that all of the 8'Sr nuclei came from the decay of 8'Rb nuclei. We assume that some of the 8Sr nuclei came from the decay of 87 Rb nuclei while the rest was present initially.The radionuclide 49Sc has a half-life of 57.0 min.At t=0, the counting rate of a sample of it is 6000 counts/min above the general background activity, which is 30 counts/min.Without computation, determine whether the counting rate of the sample will be about equal to the background rate in 3 h, 7 h, 10 h, or a time much longer than 10 h.
