Polonium Halos

I haven't written anything on Robert Gentry's claims about polonium haloes in a while.  My major piece on this topic was Polonium Halos as Evidence of a Young Earth? on my main site which covered aspects of the radioactive decay series ignored by Mr. Gentry.

However the NCSE has recently published a few articles related to the geology of these halos.

• Origin of Polonium Halos by Lorence G Collins & Barbara J Collins
• “Polonium Haloes“ Refuted: A Review of “Radioactive Halos in a Radio-Chronological
and Cosmological Perspective“ by Robert V. Gentry by Thomas A. Baillieul
