- A prudent soul might observe that many people "have become ill with

- Oops! Science suffers another sling and arrow. The 50E6 value for
- Chernobyl _did not include_ the noble gases, most of which are
- short-lived (particularly xenon-133, 133m, 135, and 135m)
- and account for 99.9+% of releases and practically none of the dose.
-
- One presumes that Mr. Roland Hipp, "Greenpeace's expert in nuclear
- issues" might have, in good conscience, provided that info. The annual
- releases from THORP must include such materials. For example, a 55-GWe
- fuel reprocessing plant would only release about 16E6 curies,
- practically all of which would be krypton-85.
-
- Again, the potential dose commitment is what is interesting, not an
- apples-and-oranges listing of curies.

-
- It would be interesting to know if these were averages for bulk
- collection of sand or "selected" hot spots.
-
- Conversion to curies per kg requires division by 37,000,000,000.
- Nothing is changed, but it doesn't look quite as scary.
-
- This posting is a wonderful example of the abuse of data.
-
- Sad......and, even sadder, predictable.
