The nonsense of Absorbed Dose

Absorbed doses of ionising radiation are defined as an average of the energy that is transferred into large volumes of body tissue. This approach is valid for considering external exposures, like X-rays or natural gamma (cosmic rays) but not for situations where radioactive substances inside the body irradiate microscopic volume of tissue selectively. Particles of Uranium and Plutonium are examples; the range of their alpha emissions is so tiny that all the energy is concentrated into a few hundred cells. Some call this kind of situation “pinpoint radiation”. Using absorbed dose to assess the potential health damage…
