[edit] Merger of cosmogenic isotope article
Seeing as this environmental radioactivity article is a broad, overview-type article, I don't think it was appropriate to merge the entirety of cosmogenic isotope into this article. Particularly when half the CI article is focused on the geochronologic applications of the nuclides. I don't see the uranium-lead dating article merged into the long lived actinides section. I agree that Be-10, Be-7, Cl-36, etc should be included in "the subject of radioactive materials in man and his environment", but not at the expense of a thorough discussion of them in their own right, in their own article. If I was going to look in Wikipedia for an explanation of what Be-10 is, how it is produced, and why we care about it, I would not expect to end up at environmental radioactivity as the end-all be-all source for that information.
Perhaps a title for the CI article more specific to their applications would be an improvement: Cosmogenic nucide dating, to follow in the style of the other radiometric dating techniques. And a See also link here. For reference, see pre-merger version of cosmogenic isotope. -- BlueCanoe 01:11, 24 June 2006 (UTC)
[edit] Comments on Main Article
The following is not a proper reference:
"For instance Busby quotes Garland et al. 1989 who reported the plutonium activity in Welsh inter tidal sediments...."
Who is Busby? And what is the paper by Garland et al? Neither are mentioned elsewhere in the article. The proper reference should be direct to Garland et al, and the full reference to that paper should given as a Reference or Further Reading at the end of the article.

[edit] Fair use rationale for Image:Puinsiltasafunctionofdistance.png
Image:Puinsiltasafunctionofdistance.png is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.
Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.
If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

I changed the decay rate for Be-10 to be consistent with the latest research of Nishiizumi et al. : Nishiizumi, K., Imamura, M., Caffee, M., Southon, J. R., Finkel, R. C., and McAninch, J., 2007, Absolute calibration of 10Be standards: Nuclear Instruments and Methods in Physics Research B, v. 258, p. 403-413 —Preceding unsigned comment added by 132.198.136.144 (talk) 19:22, 1 May 2008 (UTC)
