Abstract:
In combination, a filtration system and a fluid stream containing abrasive cutting material and radioactive cut material, said filtration system comprising:a magnetic filter having an inlet in fluid communication with said fluid stream, said magnetic filter having a first outlet for discharging material having a high magnetic susceptibility and a second outlet for discharging material having a low magnetic susceptibility, whereby particles having a high magnetic susceptibility are removed from said fluid stream by said magnetic filter, wherein said abrasive cutting material and said radioactive cut material each have a different magnetic susceptibility, and said magnetic filter separates a substantial amount of said radioactive cut material from said abrasive cutting material based on the different magnetic susceptibilities, andwherein said abrasive cutting material has a low magnetic susceptibility and said radioactive cut material has a high magnetic susceptibility.
