BRAWN team: When might we have some Strontium 90 reports? (Posted by Bill)
Now that Japan has reported Strontium 90 being found up to 80 Kilometers from the plant, that means it blew up into the atmosphere too, it seems.
NHK is reporting this tonight.
Do you have the capacity to test for it and will you?
Also: do you have access to a "base-line" pre-Fukushima set of data for Strontium 90?
I ask this because I took a look at the EPA Strontium data for milk which someone posted a link to on this forum and it seems we have got tons of it (figuratively) in our milk and environment (this is also the conclusion of the Radiation and Public Health Project whose data and peer reviewed studies may be found at www.radiation.org who tested baby teeth from children born or conceived near nuclear power plants in the United States and found EVERY baby tooth tested to contain Strontium 90).
Since Strontium 90 is a Calcium analogue and is absorbed by teeth (in utero) and bones and gets into the bone marrow and blood and hgence organs - and because it has a 29 year half life)
PLEASE let us know that you will test for it soon.
Or if not then where we might find a group like yours that will.
the data will be critical for epidemiological and environmental bioaccumulation studies - so it is a worthy endeavour to assess the increase of Stronium in our environment from Fukushima (if any, which seems a certainty if it blew up into the atmoisphere with all the iodine and cesium we are seeing)
Finally: WHY is it so hard to test for Strontium 90? There is , like, NO ONE, it seems even looking for it. Yet it is one of the worst killer cancer causing radionuclides.
Let us know asap. Thx

any thoughts BRAWM?

Sr-90 is only a beta emitter, which the germanium detectors used here will not be able to see. These detectors are for gamma rays.

Actually, Bill is correct in asking about this based on the reply by a BRAWM team member to a post I submitted which contained a link to Plutonium, Uranium, and Strontium test results posted by the EPA. Here is the reply from the BRAWM team member.

Great, thanks for finding that link. We are working to set up a detector to test for those same isotopes.
A couple points on this:
(1) EPA is not finding Pu-238, Pu-239, or U-235. These are isotopes basically only found in nuclear fuel. That is a good sign.
(2) EPA is sometimes measuring U-234 and U-238. These are naturally-occurring isotopes.
By the way, the unit conversion from pCi/m^3 to Bq/L is 1 pCi/m^3 = 3.7E-5 Bq/L.

Mark --- so you said you are or are not working to set up
a detector for Strontium 90.
I did have a few other questions in my OP but this is the main one.
The answer seemd like it MIGHT happen, but I may have missd a thread or post where you said it wasn't happening.
Anyway, thanks for the response.
I REALLY hope someone reliable is testing for new Strontium 90 and can conmpare it to past levels to see if it is rising now due to Fukushima --- any insights or info on THAT question BRAWM?
ANYONE know if strontium 90 levels are increasing here since Fukushima in milk etc?
THX
Hi Bill, in the comment I
Hi Bill, in the comment I made that was quoted by another poster, I was specifically referring to those uranium and plutonium isotopes -- not strontium-90. We've set up an alpha detector and are currently taking data to look for plutonium -- results will be out soon.
We do not have plans to test for Sr-90 since our group does not have a beta detector.

thanks, that is too bad
someone needs to get on that!
If I may ask, what does
If I may ask, what does "taking data" mean? Do you have a way to look for Plutonium particulates that may have been deposited during the "early arrivals"?
