F. Step-6

Radiation absorbed dose of source organs can be calculated using the total number of disintegration of source organs from Step-5 and S-value of selected radionuclide in OLINDA/EXM software.

First radionuclide will be selected in OLINDA/EXM for data processing as shown in **Figure 8**. Then, adult male or adult female will be selected according to patient's data for Kidney, Liver and Spleen but Sphere model can be used for the tumors as shown in **Figure 9**.

**Figures 10**–**12** of OLINDA/EXM software is shown the fitting the curve for calculation of cumulated dose or total number of disintegrations to dose calculation using the s-value from the software.
