Term
| the measured effect increases in direct proportion to the radiation dose |
|
Definition
|
|
Term
| the measured effect increases disproportionally to the dose |
|
Definition
|
|
Term
| the measured effect does not occur at all below a certain dose level, but suddenly appears at that dose level |
|
Definition
|
|
Term
| the measured effect occurs at all dose levels including zero dose |

|
|
Term
usually following high dose exposure and early response
ex radiation induced skin burns |
|
Definition

|
Term
| every radiation dose response has two characteristics |
|
Definition
linear or nonlinear
AND
threshold or nonthreshold |
|
|
Term
| the response is ___ proportional to the dose |
|
Definition
|
|
Term
| when any dose is expected to produce a response |
|
Definition
|
|
Term
| when a dose requires a threshold greater than zero to produce a response |
|
Definition
|
|
Term
| the dose-response relationship is represented by a curve and does not increase in direct proportion to the dose |
|
Definition
| nonlinear dose response relationships |
|
|
Term
| when any dose is expected to produce a nonproportional response |
|
Definition
|
|
Term
| when a dose requires a threhold greater than zero to produce a response, becoming increasingly effective per increment, until it reaches the inflection point |
