§ 20.1402 Radiological criteria for unrestricted use.
A site will be considered acceptable for unrestricted use if the residual radioactivity that is distinguishable from background
radiation results in a TEDE to an average member of the critical group that does not exceed 25 mrem (0.25 mSv) per year,
including that from groundwater sources of drinking water, and the residual radioactivity has been reduced to levels that are
as low as reasonably achievable (ALARA). Determination of the levels which are ALARA must take into account
consideration of any detriments, such as deaths from transportation accidents, expected to potentially result from
decontamination and waste disposal.
