The effective energy (related to bremsstrahlung radiation from an x-ray machine) is the monoenergetic photon energy which produces the same first half value layer in a given material as the x-ray beam.

In physics, energy is described as the ability to do work by a force, measured in joules (J). Several different forms of energy exist to describe various natural phenomena. See also Photon Energy, Rest Energy, Binding Energy, Kinetic Energy and Effective Energy. Further Reading: Basics:

(Sv) The sievert is the SI unit of a dose equivalent, which accounts for relative sensitivities of different tissues and organs exposed to radiation. The effective dose, usually measured in millisievert (mSv),
attempts to reflect the biological effects of radiation.
One sievert equals an ionizing x-ray or gamma radiation energy loss of 1 joule per kilogram of body tissue (1 gray). One sievert is equivalent to 100 rem. It is named after Rolf Sievert, a Swedish medical physicist. •
In radiology dose is the term for radiation related to the amount of energy absorbed in matter (for example absorbed dose, acute dose, effective dose, external dose, personal dose and committed dose equivalent). The SI standard unit of radiation dose is the gray. Dose refers also to the amount of medication, radiopharmaceutical or contrast medium used in diagnostic imaging. See also Deep Dose Equivalent, Critical Organ, Eye Dose Equivalent, Collective Effective Dose, Medical Internal Radiation Dose Committee, and Chronic Dose. Further Reading: News & More:
