|
Term
|
Definition
| Biologic damage occurring as a result of ionization of atoms on essential molecules produced by straight interaction with the incident radiation. |
|
|
Term
|
Definition
| Low-LET radiation interacting with biologic tissue,causing damage to a cell primarily through an indirect action that involves the production of molecules |
|
|
Term
|
Definition
| Multistage process that first involves the production of free radicals that are created by the interaction of the radiation with water (H2O) molecules. |

|
Term
| Oxygen enhancement ratio (OER) |
|
Definition
| Ratio of the radiation dose required to cause a particular biologic response of cells or organisms in an oxygen-deprived environment to the radiation dose required to cause an identical response under normal oxygenated conditions. |

Term
| Radiation weighting factor (WR) |
|
Definition
| Used to calculate the equivalent dose (EqD) to determine the ability of a dose of any kind of ionizing radiation to cause biologic damage. |
|
|
Term
| Relative biologic effectiveness (RBE) |
|
Definition
| Describes the relative capabilities of radiation with differing LETs to produce a particular biologic reaction. |
