<p>On 29/11/2018 at 17:40 a rough measurement of the irradiated target activity was performed using a geiger counter.</p>
<p>The geiger counter was a calibrated Berthold LB124, which was placed a fixed 15mm distance from each target.</p>
<p>The calibration was such that 1cps = 37kBq.</p>
<p>The LB124 counter measured a background count of 0.5cps</p>
