The physician guideline article herein provides information on opportunities to minimize doses and the risk from 
diagnostic uses of radiation by optimizing the applied procedures from the standpoint of diagnostic quality and reduction of excessive exposure doses to patients.
You will be taken into sections describe about the ionizing radiations practice of medicine, the benefit of ionising radiation to human health (modern diagnostic radiology, nuclear medicine, radiation therapy, risks to the use of ionising radiation in medicine based on the aim of managing radiation exposure, and quantify the amount of radiation, mechanism of radiation-induced biological effects.
It then be continued into how to classify the effect of radiation (deterministic, stochastic, hereditary effect), typical doses from medical diagnostic procedures, situations should be avoided on the diagnostic radiological investigations, special diagnostic procedures (children and pregnancy), reducing radiation risk during diagnostic procedure, and a table contain threhold doses for short-term or long term exposure.
