Tritium (Hydrogen-3) is prepared by bombarding Lithium-6 with neutrons. A 0.329 mg sample of Tritium has an activity of 2.42 Ci.
What is the decay rate and the decay constant (per second) of tritium?
Homework Answers
Activity is 2.42 Ci
the conversion factor is
Convert 2.42 Ci into dps
Hence the decay rate 
Note: dps represents disintegrations per second. It gives number of nuclei that decay in one second.
Mass of tritium sample is 0.329 mg or 
Molar mass of tritium is 3 g/mol
Number of moles of tritium 
Number of tritium nuclei 
The decay rate 
Hence, the decay constant is

Phosphorus-32 (P-32) is used in nuclear medicine as therapeutic
agent in the treatment of several diseases. P-32 has a half life of
14.3 days and decays directly to its ground state by emitting a
beta-minus particle. The decay table for P-32 is given. There are
no excited energy states or other radiation emitted during this
decay; therefore, P-32 is referred to as a "pure beta emitter.

A sample has a Subscript 6 Superscript 14 Baseline Upper C activity of 0.0060 Bq per gram of carbon. (a) Find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 Bq. (b) Evidence suggests that the value of 0.23 Bq might have been as much as 23% larger. Repeat part (a), taking into account this 23% increase.
