✦ Synopsis

Measurements of 99Tc in vegetables have been made. The radiochemical yield is measured by tracing the process with a known amount of 99mTc. Differences in chemical behaviour of the problem 99Tc relative to the tracer 99mTc have been found under certain conditions and the way to overcome them is reported.
