Which term refers to the radiation that occurs when an electron drops down from an outer orbit to fill a vacany in an inner orbit of the parent atom

what is a byproduct of compton interaction

annihalation radiation is used in which modality

xray photons that penetrate through the patient and strike the image receptor are called

what two interactions btw xradiation and matter may result in the production of small angle scatter

as kvp increases the total number of photons that are transmitted without interaction(penetration) increases
