Collectables

If you are interested in radioactive collectables, then an excellent resource, is a book by William Kolb and Paul Frame, titled " Living with Radiation: The First Hundred Years"  I recommend this book. Here is a brief description from the author as well as ordering information:

Whether you buy, sell, collect or are interested in anything radioactive made in the last century, "Living With Radiation: The First Hundred Years" is the best reference text available. Pictures, descriptions,
explanations, dates and measurements are included for everything from Alphatron fertilizer to Zimmer Radon Emanators, from uranium earrings, pencils and souvenirs to radioactive dishes, glasses and refrigerator deodorizers, from radio tubes, camera lenses, watches, and smoke detectors to tonics, pills, pillows and suppositories. There's even a section on quack items that claimed to have radium but did not.
Appendices are provided for a broad range of subjects including owning, shipping, pricing, measuring and evaluating the risk of radioactive materials. This privately published book contains over 250 pages with 170 pictures and a Velo binding.
