Question | Answer |
---|---|
States that ionizing radiation is more effective against cells which are highly mitotic, immature, and have a long dividing future. | Law of Bergonie and Tribondeau |
Cell that is unable to continue repeated divisions after being irradiated. | Reproductive Failure |
The unit for absorbed dose. | Rad |
Division of biology concerned with effects of ionizing radiation on living things. | Radiobiology |
Hair loss. | Epilation |
The splitting of radiation into smaller amounts over a period of time. | Fractionation |
A result of ionization and excitation, an interaction that happens directly on a critical biologic macromolecule | Direct Effect |
Reddening of the skin | Erythema |
A cell interaction that occurs when the initial ionizing incident takes place on a distant noncritical molecule, which then transfers the ionization of energy to another molecule | Indirect Effect |
The causing of genetic mutation by radiation | Mutagenesis |
