This lecture covers the fundamental equations that describe the decay of radionuclides. Basic equations and their utility are presented. Equations for mixtures, equilibrium, and branching of radionuclides are covered. Examples are provided for error evaluation from counts, activity determination, evaluation of half life, and lifetime of isotopes. Discussion of natural radiation and dating are given. Examples are provided for dating from 238U, 14C, and the Oklo reactor. The lecture time for part 1 is 44 minutes. Part 2 is around 58 minutes.
The lecture is assigned on Monday 9 January 2017 and due Saturday 14 January 2017.

ReplyDeleteThanks for PDF quiz 3. I sent some comments via e-mail.
DeleteA general comment on question 1 for PDF quiz 3 is provided. What the question is assessing are counts that can occur within one standard deviation of the average. The first thing to do is find the average. From the questions this is
ReplyDeleteDecay/second * seconds * detector efficiency
The is the total counts. The error is the square root of the counts. The range is then the average +- the square root of the counts.
