What is dose response? The basics

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

Poop and cellphones - leading into dose response

How much is too much when it comes to being exposed to something unpleasant? Using examples of fecal contamination on cellphones and cocaine on bank notes, Risk Bites begins to lay the ground for exploring dose-response. More information on the UK cellphone contamination study: http://www.eurekale

Twin dosing reduces emissions

Twin dosing is the name of the innovative process which Volkswagen is now using to minimise the nitrogen oxides in the exhaust gas from diesel engines. The new generation of diesel engines reduces NOX values by some 80%. Click here to see more videos: https://bit.ly/3cFb0gJ --- Further informatio

Three rules of thumb for using scientific models

How do you make sense of scientific models without falling into common traps? Here are three rules of thumb. This is part of a series of Risk Bites videos that tackle dose response and response models. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stu

What is a Sievert? | Andrew Maynard | Risk Bites

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

What is toxicology?

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

The naked truth about scientific models

What is a scientific model and what is it good for? As a prelude to talking about dose-response models on Risk Bites, this week's video is a primer on models -- what they are, and why they are useful. This is part of a series of Risk Bites videos that tackle dose response and response models. Ch
