>> Mr. Ney,

>> 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.
