Looking for some "field" information from those of you who have worked with thorium metal. I am not looking for calculations/laboratory conditions information. I realize that the information I'm asking for can be highly variable due to alpha attenuation from grease, oil, dirt, etc.
What ratios of beta-gamma to alpha contamination (fixed and removable) have you experienced on equipment and area surfaces (not on the metal) where thorium metal has been processed and stored?
