Table 5.7. Plutonium or 241Am Indicator Levels for Internal Dosimetry Evaluation

DOE-STD-1128-98

Thus, the ALIs found in ICRP Publication 61 (1991a) and used in the CEC/DOE

Guidebook noted above are those which would provide a CEDE of 2-rem/y instead of

current U.S. regulations of 5-rem/y.

Guidance in the CEC/DOE Guidebook can be summarized as follows:

-- When the estimated intake is below one ALI, treatment should not be considered.

-- When the estimated intake is between 1 and 10 times the ALI, treatment should be

considered.

Under these situations, short-term administration will usually be appropriate, except for

intake of materials poorly transported from the lung (class Y).
