Study Notes
Radiolysis of Water
- Radiolysis is the chemical breakup of water molecules due to radiation exposure.
- Key products of radiolysis include reactive ions and free radicals, which can lead to further chemical reactions.
Peroxidation
- Involves the reaction between various reactive oxygen species, including hydroxyl radicals and hydrogen peroxide.
- Peroxidation is a crucial process in biological systems, affecting cell membranes and leading to oxidative stress.
Color-Coding in Imaging
- Blue indicates oxygenated and perfused tissues.
- Red signifies blood vessels which are critical for nutrient supply.
- Green marks areas of hypoxia, identifying regions with inadequate oxygen supply.
