That data came from the HPGe, which really does have that precision. I know it seems like the accuracy is bad since, like you said, it could be either 0 or 2 Bq/kg. However, a Bq/kg is REALLY tiny and that accuracy (which is proportional to the length of the experiment) is good enough for this analysis. So the precision is fixed based on the HPGe and the accuracy increases with the length of time the HPGe took measurements.
- carlob 13y agoMy point stands: just write 1.0±1.0. If 1 Bq/Kg is small then giving a precision of 0.1 nBq/Kg is just plain insane.
- blueintegral 13y agoYou're right, I'll correct it.
- carlob 13y agoThat's great! I see you're not a physics major, so I apologize if I came out as aggressive. In general you want to keep 1 or 2 digits in the s.d. and align the precision of the mean accordingly.
