What are the sources for this page? As of 7 Feb 2005 I see none. This is especially troublesome consider duplicate pages elsewhere on the web (i.e. http://www.freetemplate.ws/ra/radiohalo.html ). Could someone add sources here?
[edit] Sources
I added several sources to the acticle as well as made some clarifications and additions. I hope this provides a more thorough and comprehensive reference.
[edit] Link to current sources, needed revisions
The sources for the article are not the most recent, but more important ignore some of the sources that call Gentry's work into question. http://www.talkorigins.org/faqs/po-halos/gentry.html provides a current article with citations to recent Gentry work as well as links to older and current articles that detail attempts to reproduce his observations and explain radiohalos.
The term is certainly better than what seems to be more common, po halos or polonuim halos. It appears that the halos are caused by the alpha decay of uranium, thorium, radium, radon, and polonuim. The element in the chain that Gentry pointedly ignores, even after contemporary scientists pointed to radon as the key to understanding the different halos seen.
In addition to the creationist controversy, the initial attempt to use the halos for geodating and the earlier discovery should be noted. I think this captures my current thoughts on this article. Now it requires figuring out how to organize the article and the emphasis on each point, especially in light of the controversy this purports to support. Mulp 16:47, 28 August 2005 (UTC)
