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
Some molecules are presented and then named. This screencast can be used for practice by always stopping in time. Of course, you can also have everything explained to you again. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
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
Polynomial division without remainder simply explained - theory, examples and exercise - Math Upper School & University. In polynomial division you need three steps: Divide, Multiply, Subtract. Without remainder means that there must be a 0 under the last streak. With the help of two examples and ex
This video segment adapted from NOVA describes the effect of exercise on the body and defines one measure used to gauge aerobic fitness. VO2 max (maximal volume of oxygen uptake) is a measurement of how well the body gets and consumes the oxygen that muscles need in order to sustain activity. Learn
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
The waggle dance is briefly explained. Afterwards, some exercises can be performed! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
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
