A proposed nuclear fusion reactor uses the following nuclear reaction:
He + H → He + }H
(a) Given the following masses: H (1.0078 u), H (2.0141 u), ¿He (3.0160 u), He (4.0026 u), calculate the
energy released in the fusion process. (Use 1 u = 931.5 MeV)
%3D
(b) What is the energy released per nucleon involved in the process?,
(c) Suppose a 75-kg person was exposed to 370 mSv proton radiation (RBE 10) emitted from this
reaction. How much energy is absorbed by the whole body of this person in milliJoules (mJ)?
(d) If this same type of radiation is instead used for radiation therapy, what is the biologically equivalent
dose (in mSv) if 2.56 mJ of energy is used to target a 0.015-kg tumor?
