Rad Absorption (Broken Steel)

 is a perk added to Fallout 3 with the Broken Steel add-on.

With this perk, your radiation level will decrease by 1 rad every 20 seconds (only if the player is not receiving new rads by standing in water, etc). Waiting one hour will heal 60 rads, meaning that waiting 17 hours will reduce your rad count to zero from any amount. The rate also applies to fast travel, sleeping and using the wait function itself.

This perk is useful in preventing rad build up and combined with a high radiation resistance can reduce incidences of serious radiation poisoning to few and far between. It synchronizes well with Solar Powered for healing minor health damage and minor radiation poisoning during daylight hours.

This perk makes most radiation gained from consumables entirely negligible, allowing even the potent slop served in The Pitt to be a useful alternative to stimpaks.

However, it is a very slow way of clearing large amounts of radiation after reaching level 30 (when the player rarely sleeps, as Well Rested is no longer needed).

Other methods of clearing radiation include
 * Using my my first infirmary in the player house.
 * Using Rad Away.
 * Eating punga fruit ( Point Lookout DLC).
 * Trading buffout and strange meat to the residents of Little Lamplight for cave fungus.
 * Paying 75 to 100 caps for a doctor to clear your radiation.
 * Using a healing archway ( Mothership Zeta DLC).
