Overheard: radioactive element counting

Astronomy 210, Spring Semester 2009
Cuesta College, San Luis Obispo, CA

(Overheard in lecture during an in-class activity on comparing ratios of radioactive and daughter elements in samples to determine relative radioactive ages.)

Instructor: (Seeing a student quickly counting up all elements on the worksheet) "Look at you--getting all Rain Man on this."

Student 1: "I am an excellent driver."

(Beat.)

Student 2: "You so did not just quote that movie, did you?"

Astronomy quiz question: radioactive dating

Astronomy 10 learning goal Q4.2

[Version 1]

[3.0 points.] Consider three samples (X)-(Z), with differing amounts of unstable isotopes, embedded gaseous decay products, and inert material (which is not involved in the radioactive decay process), schematically shown below.


Which one of the following choices best corresponds to the order of samples from youngest to oldest, as determined by radioactive dating?
(A) Youngest: X, Y, Z: oldest.
(B) Youngest: X, Z, Y: oldest.
(C) Youngest: Y, Z, X: oldest.
(D) Youngest: Y, X, Z: oldest.
(E) Youngest: Z, X, Y: oldest.

Correct answer: (B)
