Answer to Question #1087 Submitted to "Ask the Experts"Category: Radiation Effects — Effects on Tissues and Organs The following question was answered by an expert in the appropriate field: Q
What is the effect of radiation on the equilibrium and energy of the human cell?
A
The effects of radiation on cells depend on the type of cell and the amount and type of radiation. At doses above about 50 rad, mammalian cells can be readily killed by radiation. Smaller doses of radiation may result in nonlethal changes that can result in mutations or cancer. Cells that rapidly divide (for example, cells in the bone marrow or skin) respond differently to radiation than cells that divide infrequently or not at all (for example, cells in the adult brain or muscle).
If you are interested in the radiation response of a specific cell type or the effects of a particular type of radiation, please submit another question.
