BRAWM Team Questions Regarding Sample Collection Differences
This is the exact field in which the BRAWM team has expertice. So, I
hope they can give definative answers.
With different amounts of contamination being reported by different
teams in the same area on the same day, and different devices (air filter vs charcoal filter) giving different results, I'm curious how we can
consider any of the reported amounts as accurate.
1. Which type of air filter is accurate?
2. If true, why would a charcoal filter give a result that's 10x higher
than simple air filter?
3. Why is it acceptable for radiation measurement devices to give
significanly different results for the same volume of air? And why
is it acceptable to report those measurements?
I wouldn't accept a measurement device that tells me there's 10 gallons
of gas in my tank when another tells me there's 100 gallons.
4. How would the BRAWM team classify the 1.92 pCi/M3 level reported in
Anaheim, CA or the 2.42 pCi/M3 level reported in Dutch Harbor, AK? Do you
still consider those levels as trace/miniscule/tiny/insignificant?
With the BRAWM team reporting air results for I-131 at least 10x lower
than the CDPH (which is also using air filters), I don't know which to
believe or if the 10x difference
