Abstract
The application of ionizing radiation in medical diagnostics and treatments has been transformative in advancing healthcare for the benefit of patients. However, with these advancements comes the need to understand and mitigate the risks of ionizing radiation. While the role of radiation in medicine is undeniable, its potential to induce malignancies and genetic alterations requires careful application and understanding. This review provides an overview about the radiobiology of radiation risk, and then go through the evolution, challenges, and inherent uncertainties surrounding radiation risk models. In the end, it looks at the impact of the technological and methodological progress that has influenced the radiation protection and shapes our understanding of radiation risk. The search for references was conducted in Google Scholar and PubMed using the keywords 'low radiation,' 'radiation risk,' 'risk models,' 'radiation protection,' and 'uncertainty.'
