# §197.25. What standard must DOE meet?

- (a) The DOE must determine the earliest time after disposal that the waste package would degrade sufficiently that a human intrusion (see [§ 197.26](/cfr/40/197.26.md)) could occur without recognition by the drillers.
- (b) The DOE must demonstrate that there is a reasonable expectation that the reasonably maximally exposed individual will receive an annual committed effective dose equivalent, as a result of the human intrusion, of no more than:
  - (1) 150 microsieverts (15 millirems) for 10,000 years following disposal; and
  - (2) 1 millisievert (100 millirems) after 10,000 years, but within the period of geologic stability.
- (c) The analysis must include all potential environmental pathways of radionuclide transport and exposure.
