The subject of the graduate qualification work is âMeasurement of Lu-177 activity by absolute methodsâ. This work is devoted to the calculation of the specific activity of a counting sample of lutetium-177 using several methods. In the first case, we consider the coincidence method, where we change the efficiency by using different films. In the second case, we will use one film, but change the efficiency programmatically when processing data. In the third case, we will use the TDCR method. Compare the resulting values and calculate the uncertainty budget for the coincidence method. |
