For fast neutron therapy with mixed neutron and gamma radiation at the fission neutron therapy facility MEDAPP at the research reactor FRM II in Garching, no clinical dose calculation software was available in the past. Here, we present a customized solution for research purposes to overcome this lack of three-dimensional dose calculation.The applied dose calculation method is based on two sets of decomposed pencil beam kernels for neutron and gamma radiation.

- The NECTAR instrument utilizes thermal and fast neutrons for non-destructive inspection of large, dense objects, offering a unique radiography and tomography approach through scintillators and a camera system.
- Gamma-rays, which are produced alongside neutrons and share a similar directional path, can be considered useful rather than just beam contamination; they can be detected through gamma-sensitive scintillator screens integrated into the existing detection setup.
- This multimodal imaging technique improves depth penetration capabilities compared to traditional X-ray imaging, allowing better analysis of cm-sized objects by leveraging both neutron and gamma-ray data.
