<p>Hi Jamal,<br>
</p>
<p>Just checking:</p>
<p>1 microCurie is about 37 kHz in decays. Assuming 1% efficiency,
it's 350 Hz detector rate, quite a significant number of counts
per second, may be even smaller rate would be fine if use
few-minute detector runs. Could you educate me - why such dose
rates are not acceptable. <br>
</p>
<p>If 1 microCurie is too low for us to get any useful information
about the separation process then we should try to look for some
other goals for the run.</p>
Best regards,<br>
Pavel<br>

Our target was about 25 gram of gallium.<br>
<br>
Will the samples with 0.1 - 1 microCi of Cu-67 still be
useful to you? <br>
George will compile for us some realistic estimates and
parameters using the data from the first set of
measurements, but the level of production at 50 W beam is
certainly expected to be small.<br>

<p>Kevin had purchased a reasonably big jar of natural
gallium. We should still have the irradiated targets for
re-use; all residual activities in them are expected to be
negligible by now. We should keep the current limit as it
was before, to make the approval process easier. For the
beam time estimate it would be good to hear from VCU about
the range of Cu-67 activity that is best for their studies,
and see if we can make it (including shipping arrangements).
Better knowledge of beam energy and position is important. I
would consider a request for the line modification if needed
to make these measurements reliable.<o:p></o:p></p>
