Instructions
Use lead to block photons and borated poly to block signal to NaI detector -> now have lead sheets
Remove poly to see effect of neutrons -> Add poly back to remove neutrons
Then remove lead to see effect of photons
Add lead back but use lead sheet to find how much lead is need to block photons. Check against known data. (Lead sheet in control room cabinet)
Swap out poly for BorAl to see how much BorAl removes neutron signal, then put poly back in and see how much BorAl is needed to remove photon signal
