Monte Carlo simulation of spallation fragments cross-sections and yield for proton beam interaction with 222Rn.

Accurate determination of cross-sections for residual radionuclide products (spallation fragments) resulting from proton spallation reactions is imperative for the detection of primary and secondary particles etc. Experimental measurement of these cross-sections faces challenges due to the complexities associated with target preparation and detection of spallation fragments. Monte Carlo simulations have emerged as a potent tool for estimation of spallation fragments yield. This research, with introducing an innovative formulation method based on spallation yield, focuses on calculating the cross-section for the detection of primary and secondary particles in particle interaction with matter. Investigations indicate that the introduced method achieves remarkable agreement, ranging from 85.4% to 95.15%, with experimental outcomes at MeV energies. Consequently, this method can confidently be utilized for calculating the spallation cross-section fragments. In a case study, the spallation fragment cross-section was calculated for proton beam interaction with ²²²Rn in the range of 10 MeV to 60 MeV for the application of ²²²Rn detection. Among the 28 common spallation products of radon with the proton interaction in the energy range of 10 MeV to 60 MeV, elements ¹⁰⁶Mo, ¹⁰⁹Tc, ¹¹⁸Cd, ¹¹²Ru, ¹¹⁰Pd, and ¹¹⁴Rh exhibit dominant spallation cross-sections, emphasizing their exceptional significance.
