Trending upward...?
I look forward to the latest air results from BRAWN, but in the meantime, I was noticing on the EPA monitoring the Beta counts pretty much all trending upwards across Southern California for the past four days, especially around Los Angeles, and I'm just wondering if anyone from BRAWN or elsewhere has thoughts on why this might be. I'm also a bit surprised when I compare results between SoCal and NorCal, and also with the Pacific Northwest. One would think that -- with the way the Jet Stream typically flows -- the Northwest would be at least as high or higher in the EPA's monitoring, but it seems substantially lower all over the Northwest since Fukushima. Los Angeles seems especially high, relative to other regions.
This is not unusual for this time of year
You really need to look at the EPA historical data before
assuming "plumes" are the cause. San Bernadino (and other
So. Cal. areas) hit CPM rates of 100+ last summer as well.
I've copied the measurements for 7/2/2010 below. These
readings appear to be cyclic. With the peaks happening
around the same time of day. I would assume the readings
will rise depending on temp and the amount of polutants
in the air.
Would love to get the BRAWM team input on this, since
they are the experts in monitoring and I'm sure have
observed these patterns.
You can do your own queries here:

You'll want the parameters of "Measurement End Date/Time"
and "Beta Gross Count Rate (CPM)". Then select your date
range and monitor location.

no, the readings are higher
no, the readings are higher this year. I have looked extensively at last year's data too (where it's even available). The data you listed shows only 2 data p;oints slightly above 100. We are seeing numerous spikes above 100 and above 150 and they are lasting for a longer period of time. They are not anomolies but upward trends. If you look at a trendline for this time last year versus now, we are seeing higher levels across the board in southern california. Now, it's possible that all the EPA monitors are not working, but that seems unlikely.
It's been really hot and
It's been really hot and windy the last dew days......could that be affecting things????
check out Sacramento it is
check out Sacramento it is as high or higher than LA
Address this?
Still wishing someone would address it --- L.A. and San Diego still high....
I am in the Bay area and I
I am in the Bay area and I breath fine now, but last week and a little bit at the beginning of this week, and I do not make this up, our whole office where I worked at (concord, Ca) had the subjective sensation of lack of oxygen and tight chest, including some of my patients (I am an MD) that I asked. I had muscle pain in my legs, felt like aching, although I did not do any exercise. That peaked during early afternoon and late afternoon.
Since Wednesday we are fine, everybody including me is fine at the office.
I assume that plume whatever it was is now in LA and San Diego.
