>> I  shall attempt to be more specific and address your questions, but>> 
please  bear with me as I try to move through several programs>> established for  
monitoring uptake of  radionuclides in plants and/or>>  animals.
>>
>> In the case of phosphogypsum, the standard for  application to
>> agricultural lands was determined after analyzing the  radiological risk>> 
using dose assessment models, and then performing both  short and>> long-term 
sampling and uptake analysis of various plants and  soils>> associated with 
its use.  In remedial actions of facilities  contaminated>> with radionuclides, 
the same process is used to determine  safe levels in>> the environment.  
There have also been sampling and  analysis of uptake>> during the Three Mile 
Island accident, and also for  the purpose of>> measuring fallout from 
above-ground nuclear tests.   Testing also takes>> place around existing nuclear power 
plants.  As  you are aware, there are>> surveys to measure the amount of 
radioactivity  in sewage sludge, and>> water treatment plant sludge.  Federal  
standards are in place that limit>> the cumulative annual dose a person  may 
receive.  Also, Bob Bastian>> provided information on the  environmental monitoring 
labs that support
>> both EPA's Radiation  Program (their lab is located in Montgomery, AL)>> 
and the Nuclear  Regulatory Commission (at least one of their labs is a>> 
contract lab at  Oak Ridge Nat'l. Labs) which are routinely running soil,>> crop, 
and food  samples to evaluate radioisotope levels.  You should also>> consider  
contacting the US Department of Agriculture, and your state
>>  radiation agency to see what programs they have regarding monitoring of>> 
 uptake of radionuclides in the environment.  To reiterate, however, I  am>> 
not aware of any agency that performs real-time monitoring of uptake  of>> 
radionuclides to crops and humans.
>>
>> I hope  this provides more information on your  questions.
