Hedemann Jensen, Riso Nat. Lab. Roskild
Denmark, presented an interesting paper based on the recent ICRP 82: ICRP
PUBLICATION 82 ON PROTECTION AGAINST PROLONGED EXPOSURE - APPLICATION IN
ACCIDENT SITUATIONS, RADIOLOGICAL PROTECTION IN THE 2000s - THEORY AND PRACTICE,
Nordic Society for Radiation Protection, 13th Ordinary Meeting, Turku, Finland,
25 - 29 August 2002, it is available at: http://www.risoe.dk/rispubl/NUK/nukartikler/pdfartikler/Aabo_PHJ.pdf
Also the paper presented by Abel Gonzales IRPA-10
Conference, is very useful to understand the complete aspect on the
concept of ICRP 82 (including accidents): Decision-Making about
Chronic Radiation Exposure to the Public: New Recommendations from the ICRP
- I Think it is possible to download the paper searching the Google and
IRPA-10, anyhow I have the text to those interested

Has anyone looked

The calculations are not documented (methodology/models?) and
they violate all of my intuitions. The language is inflammatory, and the
results appear quite exaggerated. Have any of you done any recent
calculations we could use for comparison? All opinions appreciated! Ed

Ed, as a visiting, non-professional member of
this list, my first reaction is this is based on the normal LNT calculations.
I certainly think that the outer rings (0.05% increase in cancer) is in the
statistical noise, but I'm not a statistician. I'd even go so far as to say
the middle rings (0.5%) are questionable.
As to whether the entire city
would have to be demolished would be based on what the cleanup standards
should be. ALARA at what cost??? If we're seeing background radiation of
10µR/hr and the event adds 1µR/hr to that, is that any worse than moving to
Denver? So New York or Washington become Denver? Do we demolish Denver?
Is the radiation you're measuring in the brownstone façade from the
device or residual in the stone itself? What was the measurement there before?
Oh, you don't have it?
I think this is the type of press that used to
scare the stuffing out of me. Thanks to the list, I've become more
critical.
Did I pass the
test?
Cheers,
Richard
