Cf-252 source was used to define the attenuation of a signal produced by neutrons in plastic scintillator. Cf-252 source was placed in different positions along the detector surface shielded with 2" of lead and counting rate of the two PMTs was observed via dual counter ORTEC 778. Cf-252 source was surrounded by borated poly to provide collimation of about 5 cm in diameter.
Would you add to the plot the sum of the rate from each end of the PMT. In order to get it on the same scale you could divide by 2 or use a scale on the right side of the graph
Data with the counting rate from each tube added together.
