Professional geologist Tom Bailleul takes a second look at Gentry's claimed polonium haloes, arguing that there is no good evidence they are the result of polonium decay as opposed to any other radioactive isotope, or even that they are caused by radioactivity at all. Gentry is taken to task for selective use of evidence, faulty experiment design, mistakes in geology and physics, and unscientific principles of investigation and argument style.
Amateur scientist John Brawley investigated Gentry's claims directly by studying local rock samples, and concluded that there is no good evidence that these "polonium" haloes are actually produced by polonium at all, as opposed to longer-lived radionuclides such as radon or uranium.
