Question 55: 10 CFR 20.2104 (e) (1) prorates the 5-rem
annual limit on the total effective dose equivalent at a
rate of 1.25 rems per quarter for each quarter for which
records were unavailable but includes no similar provisions
for the other annual limits (individual organs, eye, skin,
extremities). Is similar proration required for doses
covered by the other limits?
Answer: Yes. As indicated in the statement of
considerations (56 FR 23383, first column), the values for
the other limits should be reduced by one quarter for each
unreported quarter. (References: 10 CFR 20.1201 (f), 10
CFR 20.2104 (e) (1))
