How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
If there is a suspicion of increased radiation exposure, there are various ways to determine it. One possibility is biological dosimetry, which can be used to estimate the level of individual radiation exposure. In the video, Dr. Ulrike Kulka explains how radiation exposure in humans can be biologic
Recent research suggests that some exposure early on to peanut products might be helpful in reducing the risks of later peanut allergies. If you're allergic to peanuts, or have a child that's allergic, you'll know how serious a condition it is. For years, parents have been advised to keep infants
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 t
Measurement technologies are getting increasingly sensitive -- but what does it mean for risk when we can measure the smallest amount of a substance in the stuff we eat, drink and breathe? Note: In talking about the hypothetical risk from the hypothetical substance Greensave, the video talks abou
What is toxicology, and why might a toxicologist just turn out to be your best friend? Risk Bites takes a look in this brief introduction to the science of toxic chemicals that might harm you, and how it's relevant to risk assessment. Risk Bites was created by Andrew Maynard, and is supported by th
A recent report from the Royal College of Obstetricians and Gynaecologists highlighted the challenges of dealing with potential but unproven risks to child health during pregnancy. While the report's authors acknowledge that most exposures to environmental chemicals experienced by pregnant women pr
How do filters remove particles from the air and reduce exposure - especially the small ones? As this Risk Bites primer shows as it dives into the science of aerosol particle capture, it may not be how you think! Air filters are an important tool for protecting health, improving air quality, and

What's is dose response, and what's it got to do with hazard and health risk? This is the first of a series of Risk Bites videos on understanding what dose response is, and why it's useful! This is part of a series of Risk Bites videos that tackle dose response and response models. This week's Ri
What is risk? And what is risk assessment? [Note from AM - I've been surprised at how tough it is to talk about risk in an accessible yet accurate way in just a couple of minutes. Looking back over this video and next week's, I can feel the paranoia creeping in that some of the basic concepts are
What's the difference between a threshold dose response model, and a no-threshold model? And what are the limitations of each? This week Risk Bites tackles the basics of dose-response models. This week's Risk Bites team: David Faulkner (Animation concepts, editing, closed captions) Andrew Maynard
