"Plutonium 238 is/was used as a primary fuel in spy satellites. The hydrazine story is a smokescreen. Pu238 decays so fast (88-yr half-life) it is used to produce thermo-electricity by a process that boils a liquid and the condensation of the liquid (mercury used to be used) creates a thermal-gradient voltage...
A micro-gram of any of the Pu species lodged in a lung can produce cancer from both or either chemical and radioactive reactions."
PU is fatal chronically (over long periods of exposure, causing cancer) in the concentration of one PU atom for a cubic foot of air. Literally, if you inhale one PU atom, ever, you are a goner. So that material could be a panic inducer if it is on board. But this is usually used only for extra-system space travel, not orbits. So is it some other material or data on board. What images was this thing transmitting? Planet X? Asteroid?
