Questions and Answers
What unit is used to measure the amount of energy absorbed by body tissue from radiation?
Grays (Gy)
How does the rate of energy release from a radiation source influence DNA damage?
A high rate of energy release causes more damage to DNA than a slower release.
Explain why it is not sufficient to only measure the amount of radiation absorbed by tissues.
It is crucial to assess the damage caused, as not all absorbed radiation results in the same level of harm.
What is the relationship between energy release in joules and body tissue in kilograms when measuring grays?

Study Notes
Radiation and DNA Damage
- Various radiation types, including energy waves and atomic particles, can harm DNA and are classified as carcinogens.
- Damage to DNA depends on the energy released by the radiation source and its absorption by body tissues.
Measurement of Radiation
- Absorbed radiation is quantified in grays (Gy), where 1 gray equals the release of 1 joule (J) of energy per kilogram of tissue.
- The real concern lies in the damage inflicted on DNA, not simply the amount of radiation absorbed.
Energy Release Rate
- The extent of DNA damage correlates with the rate of energy release from the radiation source.
- High-rate energy release results in greater damage compared to slower energy release sources.
