Sounds like they might be more inert than the pressed-marble dust block used in monumental construction (North Carolina's General Assembly Building, c. 1962) now believed to be "very slightly" radioactive.<br /><br />Thanks!Joel Raupehttps://www.blogger.com/profile/10479149035458870955noreply@blogger.comtag:blogger.com,1999:blog-6717506789759388697.post-84362759713483549852011-01-08T15:24:06.452+00:002011-01-08T15:24:06.452+00:00I've read a lot about regolith "simulants...I've read a lot about regolith "simulants" and the presence of Rare Earths in the regolith in and around Procellarum, the so-called KREEP formation, but nothing specifically about coal flyashe. It would be interesting to see if there are any studies in deep storage of the Lunar & Planetary Institute mentioning coal. Now you have me wondering about the presence of nanophase iron in coal flyashe!

Turned out inert. One of the uses proposed was for the mitigation of rising sea-level around New York City. I don't however, have the specific reference.George Myershttps://www.blogger.com/profile/07167669826031076860noreply@blogger.comtag:blogger.com,1999:blog-6717506789759388697.post-31732370478885736222011-01-08T13:06:44.744+00:002011-01-08T13:06:44.744+00:00This comment has been removed by the author.George Myershttps://www.blogger.com/profile/07167669826031076860noreply@blogger.comtag:blogger.com,1999:blog-6717506789759388697.post-56104878169025491882011-01-08T04:04:44.742+00:002011-01-08T04:04:44.742+00:00I am told that coal flyash is an good analog to lu...I am told that coal flyash is an good analog to lunar regolith; and, that both fly ash and lunar regolith contain rare earth metals. Do you know of studies on this topic by chance? Thank you.JackKennedyhttps://www.blogger.com/profile/13794874364461387428noreply@blogger.com
