Just a hint: If it were very old thorium nitrate, refined a long time ago
(50 years or so) this would be a treasure, because it would then be in
equilibrium with Ra-228 and could be used as a standard for it. Such old
thorium has been sold some time ago by a company at very high price. I
myself have enough old thorium salts.
