Radioisotope heating
Decay particles stopped inside the source and its cladding deposit their energy as heat, creating a temperature difference against the surroundings for decades.

Relations
- beta particles stopped within the source and its cladding; in practice RTG heat comes from alpha emitters (see the alpha claim)
- alpha particles stopped within the source pellet and its cladding (the RTG case)
Matrix context
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
