Revise: Radiation Hazards, Dose and RiskUV exposure also increases the risk of skin cancer. These are different consequences of exposure, so both matter when describing the hazard.
Specification Formulae, equations and hazards · Paper 3, Paper 4
The chance that a hazard will cause harm. Evaluating a risk also involves considering how serious that harm could be.
Revise: Hazard symbols and practical risk assessmentThe risk concerns the chance of that harm happening. When evaluating a risk, you also consider how serious the harm could be. The same chemical can present different risks depending on its concentration, the quantity used and how it is handled.
Name the specific hazard: ultraviolet can cause premature skin ageing and increase skin cancer risk; X-rays and gamma rays can cause gene mutations and cancer.
A greater risk does not mean that harm is certain. Support data conclusions with figures and use wording such as ‘increases the risk’.
