Re:Question on Public Limits

Check out NCRP Report No. 116.  It provides recommendations on public exposure
limits, including dose equivalent to the skin.  It also summarizes
recommendations from NCRP Report No. 91 and ICRP Publication 60.  Common
recommended limit  = 50 mSv (or 5,000 mrem) annual dose equivalent.

10 CFR 20.1301 states that the TEDE to members of the public must not exceed
100 millirem in a year.  If a member of the public can come in contact with
radioactive material that delivers a dose of 20 millirem a week to the skin
(shallow dose at 7 mg/cm^2) can I apply the weighting factors (listed in
20.1003 as remainder in this case) to the dose to find the TEDE ,

OR should I adhere to a dose that is 1/50 of the occupational limits (1000
mrem is 1/50 of the skin limit of 50 rem)

OR does the 100 mrem limit apply regardless (seems it shouldn't since it is
TEDE)

OR am I totally missing something?

Thank you for your help
