What is a Sievert, and why are they used to measure radiation exposure? Although we're exposed to ionizing radiation all the time, high levels can cause illness, disease, and even death. Yet working out how much radiation leads to specific health outcomes is complicated by the fact that different types and sources of radiation vary in their ability to cause damage, and where in the body exposure occurs makes a difference. To get around this, the Sievert was developed as a measure of biologically relevant dose - a measure of how much harm ionizing radiation might cause. It combines the amount and energy of the radiation, with the type of radiation, and the body tissues exposed, to come up with a way of estimating risk, and carrying out risk assessments. For more on how much radiation (in Sieverts) you might expect to be exposed to from different sources, check out this excellent graphic from XKCD: https://xkcd.com/radiation/ Risk Bites is supported by the ASU Risk Innovation Lab and School for the Future of Innovation in Society Produced in collaboration with Science Showcase. #radiation #risk #safety #sievert Risk Bites is your guide to making sense of risk. We cover everything from understanding and balancing the risks and benefits of everyday products, to health science more broadly, to the potential impacts of emerging technologies, to making sense of risk perception.

What epidemiology is, and why it's important? Risk Bites provides a simple introduction to what epidemiology is, and how to make sense of epidemiology studies when people's health is on the line. With Mariya Voytyuk. Written, illustrated, narrated and filmed by Dr. Mariya Voytyuk RISK BITES Risk
How do face masks and respirators prevent you from breathing in harmful particles? As respiratory protection against coronavirus becomes increasingly important, Risk Bites dives into the science of face masks and respirators, and explores what makes for good protection, whether it’s a professional
Should people who aren't scientists have a say in what science gets done, and how it is used? This week, Risk Bites takes on the knotty topic of science and public engagement. This video was created to preface a conference session on engaging publics on science and technology -- synthetic biolog
