A measure of the risk of harm resulting from exposure of the body to radiation. It is measured in sieverts (Sv), often expressed as millisieverts (mSv).
Used by AQA and Edexcel
Specification 6.6.2.3 · Paper 6
Revise: Radiation Hazards, Dose and RiskRadiation dose is a measure of the risk of harm resulting from exposure of the body to radiation. It is not simply a count of waves reaching a person. For ionising radiation, dose expressed in sieverts takes account of differences in the effects of radiation types and the sensitivity of body tissues.
Paper 5, Paper 6
A measure of a person's exposure to radiation, taking account of its potential biological harm. Radiation dose is measured in sieverts (Sv).
Revise: Radiation hazards and safetyRadiation dose measures exposure in terms of its potential biological harm. It is measured in sieverts (Sv). Safety precautions aim to keep the dose as low as possible.
AQA does not require you to recall the unit of radiation dose, but you should be able to interpret supplied doses: 1000 mSv = 1 Sv.
