Which detector did you use?

= Background

Note down the values from the background counting you started the day before.
Counting number Nbck= counts
Counting time tbck= sec
Counting speed [math]\frac{N_{bck}}{t_{bck}}[/math] = cps
Standard deviation [math]\frac{\sqrt{N_{bck}}}{t_{bck}}[/math]= cps
