<p>Radioctivity run 65 stopped before the measurement, radioactivity run 66 started after the measurement</p>
<p>Background level 120 ns/h</p>
<p>Target, stopper, the forward half of the target chamber - dismounted.</p>
<p>Approximate distance from the target position (upstream), approximate activity</p>
<p>10 cm 500 ns/h</p>
<p>25 cm 420 ns/h</p>
