“…Despite the existence of suggestions (Junaeti et al, 2022), high schools seldom find them since they are difficult to execute (Putra, 2022). Every nuclear physics experiment uses a radiation detector and an ionizing radiation source (Artiani et al, 2019). When using radioactive sources for instruction (Sriyani et al, 2021), they should typically be sealed (Hamdani et al, 2022), or if not (Ramadhan et al, 2023), they should have a short half-life and/or activities that don't require radiation protection because the sources should be handled by the students (Syafutri et al, 2020).…”
