Measurement <strong>issues</strong> <strong>for</strong> radioactive<br />
products<br />
Measurements of product quality and quantity cannot<br />
be done remotely because the equipment is too large<br />
<strong>for</strong> hot cell use and the electronics cannot survive the<br />
radiation fields <strong>for</strong> long<br />
Samples <strong>for</strong> assay must be removed but only very<br />
small aliquots can be used (20-25microliter typical) <strong>in</strong><br />
order to keep staff radiation exposure as low as<br />
possible<br />
Then large dilutions are necessary to br<strong>in</strong>g volumes<br />
up to amounts needed by the <strong>in</strong>strumentation<br />
