Since prions are found abundantly in the head, just bury or lock away the skulls and treat them like nuclear waste. Compost or cremate the rest of the body.
I think it's not, but, maybe?
missed opportunity or subtlety mastery ?
Clearly a savage had lived there amongst the nuclear barrels. Its mind altered by the radiation, chopping off those poor worker heads.
If it wasn't clear: /s
And yes prions might be dangerous but what you propose seems out of proportion.
