People on Toho Kingdom discovered that the Godzilla 1954-2000 Super Complete Works actually states temperatures for some of Godzilla's red spiral rays.

The one used against SpaceGodzilla is supposedly 900,000 degrees C and the one used against MechaGodzilla II is supposedly 1.2 million degrees C. By comparison, the temperature of a 20 kiloton nuke just a tenth of a millisecond after detonation is 300,000 degrees C (based on information I found here ).
