In diagnostic radiology, the F-factor is the conversion factor between exposure to ionizing radiation and the absorbed dose from that radiation. In other words, it converts between the amount of ionization in air (roentgens or, in SI units, coulombs per kilogram of absorber material) and the absorbed dose in air (rads or grays).
Potassium iodide is a chemical compound, medication, and dietary supplement. [4] [5] It is a medication used for treating hyperthyroidism, in radiation emergencies, and for protecting the thyroid gland when certain types of radiopharmaceuticals are used. [6]
Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [ 1 ]
If a person consumes a dose of one of these chemical compounds, his or her thyroid may saturate with stable iodine, preventing accumulation of radioactive iodine found after a nuclear meltdown or explosion.

Iodine is a chemical element with many uses in medicine, depending on the form. Elemental iodine and iodophors are topical antiseptics. [2] Iodine, in non-elemental form, functions as an essential nutrient in human biology (see iodine in biology). [3] Organic compounds containing iodine are also useful iodinated contrast agents in X-ray imaging ...
