Looking back at old calculations, I think that a person at 1 meter from a generator at the time of a catastrophic break in shielding, leading to a complete release of radioactive methane, would get a lethal radiation dose in only about 6 seconds. But the methane would be quite hot and the simultaneous release of the hydrogen into air would almost certainly lead to a small chemical explosion. I suspect the hot gas would rise away from the ground very rapidly so the chance that anyone would be exposed to a lethal radiation does, except for someone within a few meters of the generator, is quite low. Overall, if this, say, fell from an aircraft, the damage will be much less than for three tons of jet fuel. By the same logic, putting one in the basement of a tall building would probably not be wise. But our suggestion of putting them in substations would be perfectly safe.
