Quoting Uncertainties in Radioactive Decay Counts

[benedwards2020]

Is there a standard way of quoting uncertainties for say counting radioactive decay counts?

I know I can use sqrt(n)

And I know I can use fractional uncertainty 1/(sqrt(n)) too.

Is there a standard way of quoting? Apologies if this is in the wrong section

Average +/- standard deviation in the mean

round the standard deviation in the mean off to two significant digits and the average to the same least significant digit as the standard deviation.
