Can Dr. Chivers and team please translate your findings to match the German measurements? Thank you.

Dear Dr. Chivers:

is it possible to translate your iodine and telurium and cesium findings to make it the same unit (becquerels per cubic meter) so we can compare it to below data from Germany after Chernobyl?

After Chernobyl, for example, in the Munich area were significantly increased levels of radioactivity detected in the air, for example, 50 becquerels per cubic meter of iodine-131, 55 becquerels per cubic meter of tellurium-132 and 10 becquerels per cubic meters of radioactive cesium.

thank you so much.

Comparisons to Chernobyl

I was not able to reach any conclusions from the math here. I'm wondering if your team could possibly sum up the total fallout estimates for the Bay Area and compare that to Germany where we have a sense of the elevated cancer rates connected to Chernobyl? Whatever you can provide would be very much appreciated.

Since 1000 L = 1 cubic meter, you can multiply our air sample numbers by 1000 to convert from Bq/L to Bq/m^3.

If you do that, those post-Chernobyl numbers are ~10,000 times larger than our observations. What is the source of those numbers you're quoting?

please give example

sorry, my math is not good.
For the peak for iodine 8 bequerel last week, would that mean 8000 bequerel per cubic meter? That would be quite high.

Your math is right, but the

Your math is right, but the 8 Bq/L number is from the measurements of rainwater. The original poster was referring to air measurements, for which our highest measurement of I-131 has been 4.4E-6 Bq/L.

please clarify

what exactly is 4.4 E-6 Bq? Is it 4.4/100000? or one millionbiz of 4.4?

thanks.

this is a German site I found, which you can translate in English, it is somewhere in that article. thanks

I am not sure how reliable that website is.
