Should be:

One hundred grams of uranium burns out into 50-70 grams
of fine, black uranium dust.

'.. DU becomes much more radioactive when it burns. And
when it is fired, it combusts on impact. "As much as 70% of
the material is released as a radioactive and highly toxic dust
that can be inhaled or ingested and then trapped in the lungs
or kidneys." (9)
