Abstract: Background: Radiation safety awareness among healthcare professionals was essential to protect both workers and patients in settings where ionizing radiation is utilized, such as government hospitals. This study focuses on assessing the level of radiation safety awareness among medical staff at the Government Hospital in Bo. Methods: Employing a mixed-methods approach, the study incorporated quantitative surveys and qualitative interviews targeting a diverse group of medical workers, including doctors, radiologists, nurses, and other healthcare personnel. Results: The results indicate considerable variation in radiation safety awareness across different professional roles, with significant gaps particularly noted among nursing staff. Although many participants acknowledged the importance of radiation safety, their understanding of specific protective measures and regulations was inconsistent. Awareness levels were significantly impacted by factors such as years of experience, educational background, and availability of training opportunities. The analysis showed a highly significant difference (p <.001) in awareness levels based on educational backgrounds, with a mean difference of 1.392 (95% CI: 1.32 to 1.46). Notably, a significant disparity (p <.001) existed between the awareness levels of doctors and nurses compared to lab technicians and other healthcare workers, with a mean difference of 3.223 (95% CI: 2.99 to 3.45). Overall, the total knowledge level was found to be low, with a mean score of 2. A mere 12.3% of respondents reported consistently adhering to safety protocols, and a considerable proportion of medical professionals displayed insufficient knowledge (58.1%) and inadequate practice (63.8%). Comparatively, a Swedish survey indicated that 59% of medical staff had "low knowledge" regarding X-ray radiation. Conclusion: The study underscores the urgent need for comprehensive radiation safety training programs and the incorporation of radiation safety education into medical curricula to foster a stronger safety culture within healthcare settings. Implementing effective radiation safety workshops and conducting continuous assessments are recommended to enhance knowledge and compliance among medical workers, ultimately safeguarding healthcare personnel and patients from the risks associated with radiation exposure.

Abstract: Electron Spin Resonance (ESR), also known as Electron Paramagnetic Resonance (EPR), is a sophisticated spectroscopic technique that provides critical insights into the electronic structure and dynamics of materials with unpaired electrons. This experiment focuses on the application of ESR to study the stable free radical Diphenyl-Picryl-Hydrazyl (DPPH), a compound widely utilized in various scientific fields due to its well-defined resonance characteristics. The primary objectives of this study were to observe the resonance curve of DPPH, determine the resonant frequency as a function of the applied magnetic field, and calculate the Landé g-factor for free electrons subjected to an external alternating magnetic field. The experimental setup involved the use of an ESR spectrometer, a microwave source, and a magnetic field source, with DPPH dissolved in a suitable solvent to create a homogeneous sample. Data collection was performed by varying the magnetic field while monitoring the intensity of the resonance signal, allowing for the construction of a resonance curve. The results indicated a clear peak in signal intensity at a specific magnetic field strength, corresponding to the resonance condition where the energy differ- ence between the electron spin states matched the energy of the microwave radiation. The analysis of the resonance curve revealed a linear relationship between the magnetic field strength and the resonant microwave frequency, consistent with theoretical predictions. The calculated Landé g-factor for the DPPH radical was found to be approximately 1.99, closely aligning with the expected value for free electrons, thus confirming the reliability of the experimental methodology. This study highlights the significance of ESR as a powerful tool for investigating paramagnetic species, providing valuable information about their electronic properties and behavior. The findings not only reinforce the fundamental principles of electron spin resonance but also pave the way for future research into the dynamics of free radicals and their implications in various scientific domains, including chemistry, biology, and materials science. Overall, the successful execution of this experiment underscores the versatility and importance of ESR in advancing our understanding of electron spin phenomena and their applications in real-world scenarios.
