Homework Help: 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?

    Mmmmm metre, that well known unit of mass... :smile:

    Can we see the source?

    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).

    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"!
