isodosen.

/ˈʌɪsəʊdəʊs/

Etymology: < iso- comb. form + dose n.

An imaginary line or surface, or a graphical representation of one, connecting points, esp. points in the body, that receive equal doses of radiation; now always used attributively, esp. of such lines and surfaces and of diagrams depicting them.
