Additional radiohalo samples and images, provoked by receipt of two requests for information, in August of 2005.

These thumbnails are links to the larger images. Please use your backbutton to come back here after viewing one or more of them.
(Please pause your mouse over the thumbnails, to see the 'alt' filename and size...)

Some may be HTML pages, containing info on why the particular image contributes, or not, to my Radon-222 migration hypothesis for "polonium" halo formation. All images were made using a Bausch and Lomb flat-field four-objective semi-professional monocular microscope and a Polaroid PD-700 digital camera.
Images were cropped from 1024x768 with MGI Photosuite, thumbnails were generated with "Easy Thumbnails" (freeware).
