Dose Due to Neutrons

Neutrons hitting the human body deliver energy to it through elastic and inelastic collisions with nuclei, and through secondary radiation emitted by the radioisotopes produced after neutrons are captured. 

If the neutron spectrum is known in terms of energy groups, Eq. 16.16 becomes 

Although Eq. 16.16 is not normally used for everyday dose calculations, it is instructive to present it so that the reader may comprehend the various contributors to the neutron dose. 

Example 16.3 At the open beam port of a research reactor, the neutron flux at a certain power level consists of 1.6 X 10 neutrons/(m s) with energy 100

Film dosimeters and thermoluminescent dosimeters may be arranged in such a way that distinction is possible between doses due to neutrons and doses due to radiation of other types. In cases where detectors of the types mentioned previously are not available, rem meters should be used for the assessment of neutron doses.
