Hi Gary, I made a mistake in my original statement. The average American get about 360 mrem per year from all sources or radiaiton exposure, and about 55% of...
Hi Bob, Great question, but as others have pointed out, easier said than done. A Curie was/is defined as the rate of decay from 1.0 grams of Radium-226. It...
does it matter if it's absolutely pure uncontaminated water, like uncontaminated rain. we know that it won't conduct electricity, how about the other stuff?...

Right on point, Steve. There is no such thing as uncontaminated rain. Rain forms as water vapor condenses around some particle that serves as a nucleus for...
I've thought about this a bit. Can water containing solids be concentrated by boiling off the water and keeping the solids? Like concentrate a bunch of water...
Define "conductive". Granted, rainwater is more "pure" compared to groundwater in terms of dissolved minerals and salt, which gives groundwater, river water,...
Yes, George, as long as the "boiling off" process doesn't remove any of the activity. Since tritium is integrated into the water molecule itself, "boiling it...
Bob, you can't answer the question (even if the density of the water is defined, and its liquid) because you're not told enough to figure the density of the...
