N2  - Electron contamination can be defined as the undesirable electrons which accompany high energy photon beam during radiotherapy. It arises from the interaction between incident photon beam and the metallic constitunents of gantry head (such as flattening filter and collimator jaws) and the air volume separating between the treatment head and the point of mcasurement
