NEUTRONS : * Depth dose similar to photons (Co - 8 MV vs neutrons)

* High Linear Energy Transfert  High Biological effect

From neutrons to ions

* Oxygen Effect : lower radioresistance of hypoxic cells

n ° of fractions

* No repairing of cells:

* differences in radiosensitivity : treat radioresistant tumors
