But won't the range be limited by neutron decay?
- jjk166 5y agoThermal neutrons move at approximately 2000 m/s, with a half life of about 612 seconds. Decay is a non issue but scattering does put some limits (mean free path of a 14 MeV neutron in air is about 140 meters), though if your goal is just to get a signal through a wall you don't need particularly long range.
