What does dosimetry measure?

Dosimetry specifically measures the radiation dose that is absorbed by an object or a tissue, often referring to the amount of energy deposited by ionizing radiation in a given mass. This measurement is crucial in both medical and safety protocols, as it helps determine the extent of exposure to radiation and its potential biological effects.

Understanding the absorbed dose is critical for assessing the risk of radiation exposure, whether in therapeutic contexts such as radiotherapy, where precise dosing is needed to effectively treat cancer, or in occupational settings where workers may be exposed to radiation. By quantifying the dose, dosimetry provides essential information that informs safety standards, treatment planning, and regulatory compliance.

The other aspects related to radiation, such as intensity, types, and decay rates, while important in the broader field of radiation science, do not represent what dosimetry specifically measures, making the focus on dose measurement integral to the field.
