Rad Absorption (Broken Steel)

Rad Absorption is a perk

Effects
With this perk, your radiation level will decrease by 1 rad every 20 real-world seconds (this doesn't affect accumulation of new rads in any way). Waiting one in-game hour will remove 6 rads. If you had 999 rads, you would have to wait 167 in-game hours to reduce your rad count to zero. The rate applies to fast travel, sleeping and using the wait function.
