Bushong Chapter 29- Radiobiology
Deterministic effect - answer Radiation response increases in severity; occurs within
days after exposure
Stochastic effect - answer Not noticed for months/years; incidence of radiation response
increases with increasing dose
What is radiobiology? - answer The study of the effects of ionizing radiation on biologic
tissue
What is the cell theory ? - answer Cells are the basic functional units in all plants and
animals.
What do macromolecules consist of? - answer Proteins, lipids, carbohydrate, nucleic
acids
Very large molecules that sometimes consist of hundreds of thousands of atoms –
answer Macromolecules
What is the most critical and radio sensitive target molecule? – answer DNA
What is the most simplest and abundant molecule? - answerWater
What is the term for breaking down into smaller units? - answerCatabolism
What is the term for the production of large molecules from small ones? -
answerAnabolism
What is the chief function of carbohydrates in the body? - answerTo provide fuel for cell
metabolism
What is the radiation sensitive target molecule ? - answerDNA
What are the purines? - answerAdenine and guanine
What are the pyramidines? - answerThymine and cytosine
Which base bindings are allowed in DNA? - answerAdenine-thymine and cytosine-
guanine
