Fast-neutron radiobiology and radiotherapy.

The application of fast neutrons, negative pions or heavy ions will only provide an advantage for the radiotherapy of cancer if, in comparison with conventional radiations, e.g., X-rays, gamma rays and electrons, better depth-dose and collimation characteristics or specific radiobiological dose response relationships result in greater local control probabilities for tumours without increased fr...

Neutron dosimetry

R É S U M É En dosimétrie des neutrons, les situations pratiques rencontrées couvrent un large domaine d'énergie s'étendant sur plus de 10 décades. En outre, les grandeurs dosimétriques utilisées en radioprotection ne sont pas directement accessibles à la mesure. Ce dernier point est principalement dû à la variation de la "qualité" du rayonnement neutronique, exprimé au moyen des facteurs de po...

Reference Dosimetry for Fast Neutron and Proton Therapy

Fast neutrons and protons undergo fundamentally different interactions in tissue. The former interact with nuclei, while the latter, as in the case of photons, interact mainly with atomic electrons. Protons do, however, also undergo some nuclear interactions, the probability of which increases with energy. For both modalities the practical instruments for determining the reference absorbed dose...
