“…Monte Carlo simulations of d + Be therapy sources have been undertaken by [68,[95][96][97][98]. Christenson et al [95] calculated the neutron intensities for the thick-target d + Be reaction both on-and off-axis for deuteron energies between 14 and 40 MeV.…”

“…Dörschel and Streubel [96] used a Monte Carlo code to calculate characteristics of the d(13.5) + Be neutron therapy beam at the Technical University of Dresden, Germany. Comparison with measurements of fluence spectra (using track detectors), total and differential fluence and kerma as a function of depth in phantom showed reasonable qualitative agreement, although in absolute terms differences of up to 30% were observed.…”

Neutrons from the reactions of protons or deuterons of energies between 35 and 70 MeV on beryllium are most suitable for therapy because of the high yield and good penetration. Lower energy sources are used for limited applications. Proton therapy is conducted mainly in two energy ranges, viz. 60-75 MeV (exclusively for the treatment of eye lesions) and ≥ 200 MeV for general applications. Characterisation of both neutron and proton therapy beams in terms of spectral fluence is important for accurate determination of dosimetry parameters, for interpreting biological effects, for intercomparison purposes and to perform accurate radiation transport calculations.
