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?

choose a radioactive isotope used in healthcare or another field and report on how your isotope is used. Be sure to answer both of the following questions as part of your initial post: What type(s) of radioactive decay does your isotope undergo? How is your isotope used?

Applications of radioactive decay extend beyond potential terrorism. There are a number of regularly used practical applications. One such application is to use radioactive decay as a mechanism for determining the age of a sample of bones, rocks, meteorites, etc. Say you area scientist tasked with analyzing samples of moon rocks. Your moon rock contains small amounts of Uranium-238. U-238 decays into lead-206 with a half-life of 4.5 billion years. How old is your rock if 55.0% of the original...

Chapter 2 Fundamental Concepts 77 c. Your rock contains Iparent isotope A and daughter isotope B. Geochron Laborato- ries dates the rock specimen at 500 million vears old. What is the hall-life of isotope A? d. Your rock contains a parent isotope Sand daughter isotope 7. Geochron Laboratories dates the rock specimen at 200 million vears old.'What is the half-life of isotope S? Geochron has also told you that one of its lab technicians split the rock in half and...

The isotope lodine-131 is a radioactive isotope used in industrial and medical applications. It is prepared just before use because it decays rapidly through beta emission. Use the data in the table below to answer the following questions (a) Write the reaction equation. (Note m indicates an excited state of the isotope, which is generally denoted with an asterisks after the symbol, such as X*) (b) What is the rate constant for the decay? Show how you obtained this rate...

. The radioactive isotope Uranium-234 decays to Thoriu-230 with a half-life of T. Thorium 230 itself is also radioactive and decays to Radium-226 with a half-life of γ and γ > τ Although Radium-226 is also radioactive its half-life is much longer than T and γ and here we assume that it is relative stable. Consider the scenario when we start with a certain amount of pure Uranium-234, because of this chain of decays, we...

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...
