Looking at effluent concentration of a gas. uCi/mL of air out of a stack. So you would need to look at number of disintegrations in that time period over air volume. At least that was what I was thinking in my conclusion from post #11.
Correct if it were accumulating, but for this scenario we are assuming it will be "released" so there won't be a buildup to equilibrium over the 28 days it takes to get to 99%.
I don't have my notes on me. Calculating Rn-222 from Ra-226 sources for an effluent concentration on a daily basis. Used number of atoms in 10 Ci of 226 to get disintegrations to Rn-222 and then converted that by ratio to Ci of Rn-222. I think I ended up with something like 11.4 uCi which...
Does it matter? Your response and follow-up question are totally irrelevant. That's why I didn't answer your question. Obviously I posed it on this forum because I either don't have a resource available at this time or maybe no one could help.
It isn't homework. I was hoping someone would provide an answer and I would just reverse it back. Trying to determine Rn-222 activity released per day from a 1 Ci Ra-226 source. Based off a release rate of 0.000001 mL Ra-222 per day per Ci of Ra-226 and density of radon I came up with 1.5 Ci of...
TL;DR Summary: What is the activity of 0.000001 mL Rn-222?
Trying to do a quick calculation of the activity of 0.000001 mL of Rn-222 and I'm not ending up with what I expected.
