Following the adoption of those guidelines by the United 
States and other LDC contracting parties in 1978, the IAEA con- 
vened an Advisory Group on Low Level Radioactive Waste Dumping

in Jamaica. The findings of that meeting confirmed the need 
for continued validation of present assumptions with respect to 
past dumping, as shown by the definition of monitoring that was 
agreed upon: 
Monitoring we have defined as the collection of 
samples and/or data, and the analysis of samples 
and/or all the relevant data, required to demon- 
strate whether an impact of the dumping operations 
can be seen. It must be emphasized that such data 
and such interpretation cannot be simply on a yes 
or no basis, but that the operation must be done 
in a sufficiently iterative way that trends can 
be described, and that situations tending toward 69/ 
measurable impacts can be identified and controlled. 
Monitoring must report where the dumped material 
in fact is, and how its concentrations, distribu- 
tions and bio-availability are changing with time. 70/
