A radiation modelling apparatus comprises: a storage means (350, 360) containing details of material properties of at least one medium (100, 105, 110) which may undergo irradiation and details of the properties of at least one radiation beam (45a, 45b, 45c) operable to irradiate the media; a stochastic modelling kernel (340) operable to receive parameters of an irradiation and calculate a distribution of radiation (380) resulting from the irradiation using data from the storage means (350, 360); characterised by a filter (370) arranged so as to remove components comprising substantially statistical noise from the output of the modelling kernel (340).
