Current through Reg. 49, No. 44; November 1, 2024
Section 336.603 - Radiological Criteria for Unrestricted Use(a) A site will be considered acceptable for unrestricted use if the residual radioactivity that is distinguishable from background radiation results in a total effective dose equivalent (TEDE) to an average member of the critical group that does not exceed 25 mrem (0.25 mSv) per year (excluding radium and its decay products), 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). The concentration for radium in soil shall be equivalent to or below the limits set forth in § 336.356(a) of this title (relating to Soil and Vegetation Contamination Limits).(b) Determination of the levels which are ALARA must take into account consideration of any detriments expected to potentially result from decontamination and waste disposal (e.g., deaths from transportation accidents).(c) The licensee shall conduct all necessary radiation surveys and modeling, and shall provide reports and documentation to demonstrate that the requirements for release for unrestricted used have been met.30 Tex.
