Conventional detection methods require time-consuming scanning or sampling, often unsuitable for extreme environments and increasing radiation risks. Alpha Radioactivity Telemetry Technology (ARTT), a non-contact α radiation detecting method via secondary nitrogen fluorescence detection, addresses the limitations of traditional methods and has gained significant attention in recent years. However, limited research on α-induced nitrogen fluorescence under varying conditions hampers environmental corrections and quantitative analysis, constraining applications of ARTT. This article examines the dependence of α-induced nitrogen fluorescence yield on energy, pressure, humidity, and nitrogen–oxygen ratio, presenting measurements for all major 2P system emission bands. The results indicate that (1) fluorescence yield remains unaffected by deposited energy or α-ray energy within 1.5–4 MeV, (2) yield dependence on pressure and humidity aligns with theoretical expectations, but deviates for nitrogen–oxygen ratios, and (3) temperature has minimal impact, with a 30 °C variation around 25 °C affecting fluorescence yield by less than 5 %. In contrast, at 1 atm pressure, the yield of air is several hundred times greater than at zero pressure. At 25 °C, the yield of dry air is 1.4 times that of air at 100 % RH. And the one of pure nitrogen is over ten times higher than the gas with 20 % nitrogen and 80 % oxygen.

At the same time, different types of ion beam irradiation could produce different primary knock-on atom (PKA) energy spectra. PKA energy determines cascade damage sizes and defect clustering distributions, which may influence the irradiated materials’ long-term microstructural evolution and mechanical properties. This work used SRIM and Geant4 software to investigate the PKA characteristic produced by 1 MeV different noble gas ions and neutrons in the silicon carbide. The PKA energy spectra and weighted energy spectra of C and Si are calculated, respectively. The simulation results show that the PKA energy spectra calculated by the two kinds of software have obvious differences, but the weighted average PKA energies are close to each other. Simulation results verified that the weighted average PKA energy of Kr and Xe ion irradiation is close to that weighted average PKA energy spectrum for neutron irradiation of advanced reactors.
