Radiobiology
The study of the biological mechanisms and health effects of ionizing radiation acting on living cells and biological tissues.
Governing formula
DNA Double-Strand Breaks (DSB) ~ 35–40 per Gy per Cell
SI unit
Gy (Dose Response Units)
In depth
Investigates direct ionization of DNA molecules and indirect radiation damage via water radiolysis producing hydroxyl free radicals (OH•), analyzing cell death mechanisms (apoptosis, mitotic catastrophe).
Examples in the real world
Evaluating DNA double-strand break repair pathways following radiotherapy exposure.
