14C is a radioactive isotope with a half life of 5.73x10^3 years. Radioactive decay is first order process and the amount of 14C present in an object can be used to determine its age. How long does it take for for 90 % of the 14C in a sample to decompose?

A Radioactive Isotope is 1. Time for half of a sample to decay from parent isotope to daughter isotope for radioactive atoms 2. The technique of getting the age of something by using unstable isotopes 3. An element that has unstable nuclei and will transform itself into another element 4. The process of an element transforming into another element by changes of its nucleus

All radioactive decay processes follow first-order kinetics. The half-life of a gamma producing radioactive isotope is 2.4 hours. This isotope is used in a medical scan and enough of the isotope is given such that a heart scan can be done? If 0.75 ng of the isotope is administered, how ng of the isotope remains in the patient after 3.5 days?

Radioactive decay is a first order process. The most commonly used isotope in human scintigraphical procedures is 99mTc, which has a half- life of 6.0058 hours. A person was injected with 99mTc methylene phosphonate containing 13.2 × 10-6 g of 99mTc to image bone tissue and an image was obtained 75.0 minutes (1.25 h) later. What is the concentration (molarity) of 99mTc remaining at this time? ( 99mTc has a molar mass of 98.906 g /mol. Assume that the person...

17. If it takes 3.4 years for a radioactive isotope to decay to 1/16 of its initial value, what is the value of k for the isotope? A. 0.82 years! B. 0.69 years! C 0.051 years D. 0.20 years! E 0.92 years

7.3 The decay rate of the isotope carbon-14 (14C) is often used to establish the date on which carbon-containing matter died. In the upper atmosphere, cosmic radi- ation synthesizes 14C. This process balances the loss of 14C through radioactive decay. Living matter, which exchanges carbon with atmospheric carbon diox- ide and maintains its 14C level, produces 15.3 disintegrations per minute per gram of carbon it contains. Dead organisms no longer exchange carbon with the atmosphere, and the 14C content decreases...
