Combustion would generate plutonium dust, which was every bit as lethal as Fromm had told them.

In 1957 a fire burned plutonium dust in the facility and sent radioactive particles into the atmosphere.

The bank of 620 filters in the system that prevented plutonium dust from reaching the atmosphere during normal operations had ignited.

The doctors say they breathed plutonium dust into their lungs.

The fallout from this kind of bomb won't be irradiated debris, but actual plutonium dust.

The excavation would have to be contained in sealed buildings to prevent plutonium dust from blowing around the desert, engineers said.

No fission, but the plutonium dust is spreading through half the ship.

Of course, that could spread plutonium dust all over the surrounding countryside, which might upset the locals.

The radiation from even a small amount of plutonium dust inhaled into your lungs will give you lung cancer.

I might hit the radioactive target by accident and aerosolize some plutonium dust.
