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 />
