My quote in the past has been:   if someone does't have any Potassium-40 in 
their body, they have been dead for a long time.  As we all know, thier is 
no life without radioactivity.

As a footnote to the thread on granite, Brazil nuts, etc. the test source 
that I use for demonstrating the use of a Geiger counter is an ordinary pill 
bottle containing the usual potassium chloride tablets prescribed as a 
supplement for patients on antihypertensive medications that include 
diuretics. A typical 3 cm x 6 cm pill bottle filled with these tablets makes 
quite an impressive display. Think of the millions of people who are 
ingesting these little radioactive sources very day! Scary, huh?
