What does a linear relationship indicate on a dose-response curve?

A linear relationship on a dose-response curve means the biological effect increases directly in proportion to the radiation dose. The line is straight, so doubling the dose leads to a roughly double amount of response, with the slope reflecting tissue sensitivity. In a simple linear model, zero dose yields zero response, and there’s no need for a threshold before effects appear. This is why the statement that the biological response is directly proportional to the dose best describes a linear dose-response.
