### _Mayday_

NOTE: This is not homework, but if you feel it is in the wrong forum then move it. I didn't know a better forum that it could go in.

I want to construct a table of results (minus the results for now) that is related to how the count rate on a geiger muller counter varies with distance with a radioactive isotope. I would appreciate some suggestions of table headings. Here are a few I have already come up with, any thing you think I could add?

Distance/cm
Count Rate (or activity)
Background Count
Corrected Count rate

I would like to incorporate the inverse square law, but I am unsure how to do so. I want to measure the intensity or see how it varies. Would that just be $$\frac{1}{d^2}$$

Thanks!

Have a column of d^2 times Intensity. Test if its entries are constant for varying d.
