www.epa.gov/narel, environmental radiation data


The above link doesn't work.  I've had a cursory look and think that  this is 
the link to the data that is referenced in the article.  
_http://www.epa.gov/narel/radnet/erdonline.html_ (http://www.epa.gov/narel/radnet/erdonline.html) 
 
The article states SNIP>The EPA measures levels of beta-emitting  
radiation in rainwater each month at about 50 U.S. locations. Since the late  
1980s, average beta levels have risen about 40 percent around the  nation 
<SNIP
 
Which has confused me, the latest report that I veiwed briefly only had  data 
on the Gross Beta in Airborne Particulates, it did not have the data for  
Beta Activity in Precipitation although it did have a short summary stating how  
and when these measurements were made.
 
What I find most interesting is that the summary report I viewed did have  
data for 11 results for Sr-90 in Pasturised milk over the quarter.  Given  Mr 
Mangano's statement SNIP>The EPA finding that beta levels are rising  
corresponds to our research 
group's study of Strontium-90 in baby teeth, the  levels of which jumped 
around the nation since the late 1980s.<SNIP  It seems strange that there 
isn't a correlation between Sr-90 levels in Milk and  the increase in Sr-90 
levels in baby teeth.
 
If anyone can point me in the direction of the data for Beta Activity in  
precipitation, or where I might find the data in the EPA reports in an easier to  
use form e.g. Excel, I would be grateful.
