In a dose-response curve, which parameter is typically plotted on the x-axis?

In a dose-response curve, the dosage of radiation is typically plotted on the x-axis because this format allows researchers to assess how different levels of radiation exposure affect the biological response of cells. By plotting dosage on the x-axis, it becomes easier to observe the relationship between the amount of radiation administered and the resulting response, whether that response involves cell mortality, mutation rates, or any other biological effect being measured.

This arrangement is crucial for evaluating how varying doses can lead to different outcomes, enabling scientists to establish thresholds and understand the sensitivity of the cells to radiation. The ability to visualize this relationship is fundamental in fields such as pharmacology, toxicology, and radiobiology, where understanding the impact of varying doses is essential for developing safe and effective treatments.
