Dose 2016

Calculation vs measurement of absorbed dose Measurement (of ionization ) only at time of delivery of dose For retrospective or planned dose need theoretical description Calculation requires description of radiation fields in terms of sources of particles, their interactions and a description of receptors •Allows calculation of flow in and out of a volume of interest Deterministic •Particles subject to transport equations so can

calculate values at any point in time Monte Carlo approaches (stochastic) • Track individual particles
