Air quality results question

Submitted by Anonymous on Thu, 2011-03-24 16:48

What a great real time data gathering opportunity! I had a few questions about air quality:

- can you put air quality results in context of EPA air quality guidelines for the specific isotope exposures, since the main concern is about specific isotope decay instead of total radiation exposure

- were the air quality samples collected during constant rainfall, and would you expect to see a difference during no rainfall?

Thanks for posting the fascinating results

The air samples were collected sometimes during rainfall, sometimes shortly after or before rainfall. We expect rain to have a strong effect on the measured radioactivity in the air, as the rain will scrub out particles from the atmosphere. Conversely, we expect the concentration in the rain to be much higher when it starts raining, than when it has been raining for some time already. We are hoping to evaluate this effect more specifically, and perhaps be able to explain some of the jumps in our measurements.
