Do all gamma rays have the same energy during a given nuclear reaction? Updated 2025-06-17 +Created 2024-08-14
The following cobalt-60 diagrams suggest that some lines are clearly visible in specific nuclear reactions:

They are stopped by:Therefore, alpha emitters are not too dangerous unless ingested.

Gun-type fission weapons don't work with Plutonium-239 because of the presence of Plutonium-240 as an impurity which leads to fizzle.

Gamma spectroscopy of a Uranium ore
. Source. Several points of the Uranium 238 decay chain are clearly visible.
A nuclear reactor made to produce specific isotopes rather than just consume fissile material to produce electrical power. The most notably application being to produce Plutonium-239 for nuclear weapons from Uranium-238 being irradiated from Uranium-235-created fission.

Because you can generate plutonium-239 from uranium-238 in a breeder reactor, and then separate the plutonium-239 from the Uranium simply by using chemistry methods because you've created an element with different valence electrons.
Isn't it somewhat funny that it is easier to purify a synthetic element than a naturally occurring one?
This isotope shows up as an inevitable contaminant in Plutonium-239 for nuclear weapons, because it emits neutrons too fast and makes it harder to assemble the critical mass without fizzle.
It is the presence of this contaminant that made implosion-type fission weapon a necessity: Section "Gun-type fission weapons don't work with plutonium".
Plutonium-240 is a contaminant.
