Eighty years after Hermann Müller received the Nobel Prize for his discovery that radiation can cause genetic mutations, the scientific model based on his work, known as the Linear No-Threshold (LNT) model, is being scrutinized. The LNT model posits that any level of radiation exposure has a corresponding risk of harm, but recent challenges suggest its foundation might be flawed. This controversy has gained attention partly due to an Executive Order from the Trump Administration, which instructed the Nuclear Regulatory Commission to reconsider its reliance on the LNT model. Despite these debates, Radiation Safety Officers continue to practice caution by ensuring exposure levels remain well below regulatory limits, emphasizing the importance of safety over theoretical arguments about radiation risk. The article argues that while scientific understanding may evolve, the commitment to safeguarding public health remains unchanged.
