Atom Wikipedia
The number of protons in the nucleus, called the atomic number, defines to which chemical element the atom belongs: for example, each copper atom contains 29 protons. The number of neutrons defines the isotope of the element. Atoms can attach to one or more other atoms by chemical bonds to form chemical compounds such as molecules....

Someone absorbing 1 gray (100 rad) in a small amount of tissue, such as a thyroid gland, will absorb much less total energy than someone absorbing 1 gray (100 rad) throughout his or her entire body. Thus, when speaking of absorbed dose, it is crucial to know the amount of tissue being exposed, not simply the number of gray or rad....
Inhomogeneity OzRadOnc
Lung is made up of soft tissue and has an equivalent atomic number similar to soft tissue. It contains alveolar air spaces and is therefore less dense than other soft tissues. The reduced density leads to decreased attenuation of the primary radiation beam, which in turn leads to decreased production of scattered radiation....

So the most common form of carbon's mass number is 12. (Electrons have so little mass that they do not appreciably contribute to the mass of an atom.) Carbon is a relatively light element. Uranium (U), in contrast, has a mass number of 238 and is referred to as a heavy metal. Its atomic number is 92......

How Does Radiation Affect Humans?
Ionizing radiation, by definition, "ionizes," that is, it pushes an electron out of its orbit around an atomic nucleus, causing the formation of electrical charges on atoms or molecules. If this electron comes from the DNA itself or from a neighboring molecule and directly strikes and disrupts the DNA molecule, the effect is called direct action ....
