Radon price: $4/m ? Radon price:$4/m ??

I'm doing some research on Radon. I have to put together a PowerPoint presentation that describes its origins, properties, characteristics, etc. (Each student was assigned a different element.)

One piece of information I'm required to report on is current price to purchase a sample of the element. I have found only one source that mentions a purchase price for Radon, and it says "Radon can be purchased for approximately $4/m." - without further explanation. What is "m"?? I assume it must be a unit of volume or mass, but if so I'm not familiar with it. Any ideas?

Sorry, I should have posted that. The actual quote is "Radon is available at a cost of about$4/m."

edit: That same source has a table above the text which states that the cost is "$/100g" (no numeric value is given). Last edited by a moderator: Hmmm... I just found another source that says: "Radon is available at a cost of about$4/m Ci."

I know that Ci is a Curie, measuring radioactivity. Could "m Ci" mean mCi: a milli-Curie?

edit: second source is http://www.speclab.com/elements/radon.htm

That would be right.

Woohoo! That makes a lot more sense than "m"!
