# Radon price: $4/m ? 1. Mar 31, 2005 ### Bruce Bacher 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? 2. Mar 31, 2005 ### brewnog Mmmmm metre, that well known unit of mass... Can we see the source? 3. Mar 31, 2005 ### Bruce Bacher Yes, of course! 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: May 2, 2017 4. Mar 31, 2005 ### Bruce Bacher 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

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