The energy released per kilogram of nuclear fuel in a fission reaction is 540 000 GJ540\ 000\text{ GJ}540 000 GJ.
The energy released per kilogram of fuel in burning wood biomass is 0.018 GJ0.018\text{ GJ}0.018 GJ.
Calculate the ratio of the energy released in fission compared with the energy released in burning wood biomass.
Use the equation:
ratio=energy released from fissionenergy released by burning wood biomass \text{ratio} = \frac{\text{energy released from fission}}{\text{energy released by burning wood biomass}} ratio=energy released by burning wood biomassenergy released from fission94 exam-style questions on Edexcel GCSE Physics 6.5 Uses and dangers of radioactivity, covering 6.5.1 Uses of radioactivity, 6.5.2 Dangers of ionising radiation and precautions, 6.5.3 Half-life and radiation dangers, 6.5.4 Safety precautions for radiation exposure, and 6.5.5 Contamination and irradiation.
