English
Applications of polonium are few, and include heaters in space probes, antistatic devices, and sources of neutrons and alpha particles.

It is also easier for unstable nuclei to absorb neutrons when the neutrons are traveling at a certain speed.

The simple act of making an apple pie is extrapolated into the atoms and subatomic particles (electrons, protons, and neutrons) necessary.
en.wikipedia.org
When nitrogen is hit by neutrons, it emits high energy gamma rays that can be detected by simple radiation detectors.
en.wikipedia.org
These occur when atoms react with natural neutrons (from cosmic rays, spontaneous fission, or other sources), or are bombarded directly with cosmic rays.
en.wikipedia.org
To be effective, moderator materials must thus contain light elements with atomic nuclei that tend to scatter neutrons on impact rather than absorb them.
en.wikipedia.org
These fast neutrons do not cause fission as readily as slower (less energetic) ones.
en.wikipedia.org
Spallation processes in the target produce the neutrons, initially at very high energiesa good fraction of the proton energy.
en.wikipedia.org
Because uranium-235 releases more neutrons than it absorbs, it can support a chain reaction and so is described as fissile.
en.wikipedia.org
Also, by being bombarded with neutrons, each lithium-6 atom splits into one tritium atom and one alpha particle.
