As a graduate student I did a lot of work using radioactive materials, so I have some idea what a billion Bq means!
Tom Clancy told a tale in one of his books (Sum of all Fears?) of nuclear physicists trying to get their publications about nuclear explosions past the government censors by saying “Consider a neutron star with a flux density of ‘large number’ of neutrons per cubic centimeter ...” (or something like that).
Got past the censors just fine.
Except that anyone who knew anything about neutron stars (a group of people who do not include me) knew that the neutron density inside a neutron star was nowhere near that high, therefore, it must have been an H-bomb going off.
